# Difference between volume and capacity

Volume and capacity are two concepts that refer to the space that anybody can occupy. Both are interrelated in view of the fact that they are properties that bodies possess in their different states. In this article, we will outline the definitions of volume and capacity, in order to point out the differences that follow from them in order to provide readers with a clear and precise description of these important concepts. The main difference between volume and capacity is that volume is a defined space of an object that it covers, while capacity is a measure of an object’s ability to contain another substance.

## Key differences

• Volume is a real definite space that covers matter, while capacity is the ability of one object to hold another object.
• Volume refers to the total measurement of a closed object; on the other hand, capacity is defined as the volume of the container.
• Volume refers to the space that an object occupies, while capacity refers to the space it contains.
• The calculation of the volume is the multiplication of the length, the width and the height of the object, while the capacity is mainly calculated in cc or ml.
• To calculate the volume of a body is to measure how much it occupies while calculating its capacity is to measure how much it fits in it.
• Volume is a specification of solid and hollow objects; on the other hand, only hollow objects have the capacity.
• The unit of measurement for volume is the cubic meter while the unit of measurement for capacity is the liter.
• The volume is three-dimensional, it covers three sides of the object; conversely, capacity is not three-dimensional.
• Volume is the place in a body that is given space; on the other hand, the capacity of an object means that we can contain another object in it.
• Volume is the mass and size of a body while the capacity of a container or object is the amount of volume that fits inside it.
• Volume is measured in cubic meters; conversely, many units are used to measure capacity such as liters, pounds, gallons, milliliters, etc.
• Volume is the character of every object; on the other hand, all objects do not possess the ability.
• Volume is a term that applies to solids, liquids, and gases, while capacity is a term that has liquid specifications.

## Volume vs capacity

A volume is a definite form of a covering substance; Ability is the ability of an object to handle another object on it. A volume is the place of an object in each space, while the capacity of an object means that we can place another object in it. The full size of the container is called the volume; on the other hand, the capacity is the volume of the container. The SI unit of volume is the cubic meter, while the units of variation capacity, such as liters, gallons, and pounds. Volume is a three-dimensional quantity, while capacity is not a three-dimensional quantity.

When the length, width, and height of an object are multiplied, we get the volume as the result. Rather, the capacity is oriented to cc and ml. Volume is indicated by V, while capacity is indicated by C. Every object has volume. Every object does not have the ability. Volume is the character of solid and hollow objects. The capacity of hollow objects is easily measured. Volume is the specification for solid, liquid, and gas. On the other hand, the capacity is liquid in nature.

## What is volume?

Volume refers to the sum total of the space held by an object. When a solid object covers a specific region, its measurement is called volume. It is defined as the total amount of anything that covers a space. It is just the space that a solid, liquid, or gaseous substance covers. The full size of a closed container is called the volume. When we multiply the length, width, and height of a substance, the result is volume. Since it covers three sides of the surface, it is three-dimensional.

Volume is indicated by the symbol V. The SI unit of volume is cubic meter (m 3 ). The dimension of the volume is [L 3 ]. In the metric system, the unit of volume in liters (L) and one liter is equal to a cube of 10 centimeters. A small amount of volume is measured in milliliters (ml). However, a large quantity is measured in megaliters. The volume also finds its units in the traditional system, which includes a cubic yard, cubic mile, cubic foot, cubic inch, tablespoon, teaspoon, quart, gills, pint, gallon, minimum, peck, cord, barrel, and dram of liquid. .

Fluid displacement is a method used to measure the volume of a solid, independent of the solid, that has a regular or irregular shape. The volume of gases is determined by the displacement of liquid matter. When two substances dissolve in each other, the combined volume is not additive. In thermodynamics and fluid dynamics, volume is a primary element; their role is different in both branches. In thermodynamics, it is an essential parameter of the state function. The ideal gas law relates to volume, temperature, pressure, and ideal gases.

Volume can be defined as the space that a body occupies in a given place, that is, the amount of space that its matter occupies and that cannot be occupied by another body at the same time. Likewise, the space or volume occupied by matter can be quantitatively measured in any of the various units of measurement.

The International System of Units establishes the cubic meter as the main unit of volume. The cubic decimeter and cubic centimeters are also found. In solid bodies of regular shape, the volume is determined by its dimensions and is obtained by applying a mathematical formula to obtain the result of its three dimensions (length, width, and height).

Finally, the volume indicates how much space an object occupies, that is, it is the mass and size of a body. Therefore, volume is a quality that can be measured, any object in the world has volume regardless of its size and shape or its state.

## How is volume measured?

According to the International System of Units, the cubic meter for volume has been established as the main unit. In other cases, you can choose the cubic decimeter and cubic centimeters.

In relation to solid bodies of regular shape, the volume is determined through its dimensions and is obtained by applying a mathematical formula to obtain the result with its three dimensions: length, width, and height.

## What is capacity?

The volume or mass of a container is called the capacity. It is defined as the capacity of a hollow object to contain other matter that can be of any state of matter. It is an object in which we can place another substance. Capacity and volume are closely related but do not convey the same idea. The interior of the container is its capacity, that interior is called volume. The space available in a container, in which other matter can be filled, is capacity.

When we fill the air in a balloon or a container, it conforms to the shape of the balloon. Suppose a tank is full of water, the volume is the space occupied by the water and the interior of the tank, and the amount of water required to fill the tank is its capacity. Capacity is measured in different units including gallons, liters, and pounds. Capacity is the most identifiable character of liquid and pourable substances.

Capacity is the property of being able to contain a certain amount of something up to a certain limit. The main unit for measuring the capacity of an object is the liter (L) but this is a divisible unit. Additionally, there are the multiples, which are the units to express capacities larger than the liter, and the submultiples, which are the units to express smaller capacities.

In this sense, the derived units are the kiloliter, the decaliter, the hectoliter, the deciliter, the centiliter, and the milliliter. It should be noted that a liter is defined as the volume occupied by a mass of one kilogram of pure water at a temperature of 4º C and 760 mm of atmospheric pressure. Under these conditions, 1 liter is equal to 1.000028 dm 3. In short, capacity is understood as the empty space of something that is sufficient to contain a body in any of its states.

Inattention to the aforementioned, it can be said that capacity and volume are terms that are closely related because they both refer to the space that a body occupies. Therefore, the main differences between volume and capacity are:

## How is capacity measured?

The main unit by which the capacity of an object is measured is the liter or L, although this is a unit that can be divided. In turn, there are multiples, which are units that express capacities that are larger than the liter and submultiples, which are units for express smaller capacities, where some examples are: kiloliter, decaliter, hectoliter, deciliter, centiliter and milliliter.

## Conclution

Both volume and capacity are the quantities of matter that are measured. Volume is a real space that an object covers and is measured in cubic units. Capacity is the ability of an object to allow another object to hold onto it and measure itself in different units.
