What is a cubic meter?How to use the cubic meter calculatorHow to calculate the cubic meters of a box or spaceFAQsWith the cubic meter calculator, you can convert any volume unit to cubic meters. On top of that, you can also calculate the cubic meters of a box of a known size, regardless of the length units you've got! If you want to convert from cubic ft to cubic meters, or convert cubic meters to cubic feet, or any other combination, this is the fastest and easiest way!
So go ahead and use the calculator to calculate cubic meters and convert from and to cubic meters, cubic feet, and whatever other unit of volume you want!
What is a cubic meter?
First things first, we need to make sure we all know what a cubic meter is. A cubic meter is the SI unit for volume. It is the obvious choice for volume, given that the volume is the 3D space taken up by an object. In fact, this is the clearest when we think about a box. In that case, the formula for its volume would be:
volume = length × width × height
If we use meters for length, width, and height, it makes sense then that the final units for volume would be
meter × meter × meter = meter³
That is why we use the cubic meter and its derivative units (cubic kilometer, cubic centimeter, etc.) as the international unit for volume. However, it is not the only one, and in places like the USA, the imperial system is more prevalent. In the imperial system, we find units such as the cubic inch, the cubic mile, and, most similar to cubic meters, the cubic foot.
Just like knowing different languages, being able to convert from cubic meters to cubic feet and back from cubic feet to cubic meters is essential. In fact, the more units we can convert from and to, the better! Before we learn how to calculate cubic meters from any other unit, we should take a look at some of the common abbreviations:
 Cubic meters: m³
 Cubic centimeters: cm³, cc
 Cubic kilometers: km³
 Cubic feet/foot: cu ft, ft³
 Cubic inches: cu in, in³
How to use the cubic meter calculator
The cubic meter calculator can be thought of as several calculators in one. It has two main modes: conversion and calculation, but they can also be used simultaneously with some clever operation. Assuming you do it correctly, this calculator can:
 Calculate the cubic meters of a box;
 Calculate the cubic feet of a box;
 Calculate the cubic inches of a box;
 Calculate the cubic centimeters of a box;
 Convert cubic meters to cubic feet;
 Convert cubic feet to cubic meters (cubic ft to cubic meters);
 Convert cubic inches to liters;
 Convert gallons to cubic meters; and
 More!
Even if it looks like the ultimate conversion tool, this cubic meter calculator is best suited for... well... calculations involving cubic meters, duh! If you are looking for the ultimate converters, check out the volume conversion, the area converter, and the distance converter, all closely related to this one but slightly more focused on pure conversion.
It is now time to see how to use the cubic meters calculator by Omni Calculator to compute the volume of a box using any mix of units:
 Select the units and input the value for the length.
 Select the units and input the value for the width.
 Select the units and input the value for the height.
 At the bottom of the calculator, you will see the resulting volume in 2 different units (by default, cubic ft and cubic meters). Feel free to change if you want to.
It's all effortless and very straightforward. You can mix and match units as you see fit, and the results will always be in the units you choose, from cu ft to cubic meters to gallons or liters. But we can make it even easier if you don't need to calculate the cubic meters and just want to convert volume, for example, from cubic feet to cubic meters.
If you want to use the cubic meters calculator as a volume converter, you have even fewer steps to follow:
 Collapse the top section of the calculator.
 The fields for width, length, and height will be hidden because they are not needed.
 Select the unit you want to input and enter the value in the top field for volume.
 Automatically, the tool will calculate the cubic meters equivalent of the volume.
It could not be easier! You don't need to remember any conversion factors, do any math or wait. Just select your unit, input the value, and enjoy the result!
How to calculate the cubic meters of a box or space
"Sure, that's fine, but how do you calculate the cubic meters of a box?" You might be saying. Maybe you don't want to use our wonderful calculator. Perhaps you want the knowledge as a backup, or maybe you're preparing for an exam. We won't judge; we only help! So, if you want to learn how to calculate the cubic meters of a box, here is how to do it:

Take the values for your box's length, width, and height. If possible, use meters.

If you haven't used meters, convert each of them individually to meters.

Apply the volume formula for a box:
volume = length × width × height

Your results should now be in cubic meters. Apply the conversion factor if you want another unit.
As you can see, it is not complicated, but it is needlessly timeconsuming when you have a nice tool like this one, which we created at Omni Calculator.
How many cubic centimeters in a cubic meter?
There are 1,000,000 cubic centimeters in a cubic meter. To remember this, you can think about converting meters to centimeters for each of the three dimensions: length, width, and height. One meter has 100 cm, so multiplying that by itself three times, a m³ has 1,000,000 cm³.
How many cubic feet are in a cubic meter?
There are 35.315 cubic feet in a cubic meter. Converting from cubic meters to cubic feet is the same as converting from meters to feet for each of the three dimensions: length, width, and height. One meter has 3.281 feet, so multiplying that by itself three times, one m³ has 35.315 cubic ft.
How many liters in a cubic meter?
There are 1000 liters in a cubic meter. To remember this, you can think about cubic decimeters and liters since they are both the same size. One cubic meter (m³) is 1000 dm³, so since liters and dm³ are the same, there are 1000 liters in a m³.
How many gallons in a cubic meter?
There are 264.17 US gallons in 1 cubic meter, and there are 219.97 UK gallons in 1 cubic meter. You can perform any conversion from cubic meters to gallons by following this instructions:
 Find out if you want US gallons or UK gallons.
 Multiply the number of cubic meters by the conversion factor (264.17 for US gallons) and (219.97 for UK gallons).
 The result will be expressed in your chosen unit.
What is cubic meter?
A cubic meter is a unit of measurement that corresponds to the volume of a square box with 1 meterlong sides. This means a little over 3 ft per side. You can calculate the volume of said box by multiplying all three dimensions together:
1 m × 1 m × 1 m = 1 m³
Another way to visualize a cubic meter is to convert it to other units. One cubic meter is the same as:
 1000 liters;
 264.17 US gallons; and
 35.32 cu ft.
