How Many Cubic Feet Are in a Cubic Yard?

When setting up a cannabis garden in your home or a commercial facility, volume measurements may be necessary when dealing with bulk soil, maximizing the vertical growing space, and determining the minimum air exchange for your grow room.

Beyond the world of cannabis cultivation, understanding common units of volume such as cubic feet, cubic yards, fluid ounces, cups, pints, and gallons is important. Here, we show you how to convert cubic feet to cubic yards and vice versa.

TL;DR (Too long; Didn’t read): There are 27 cubic feet in a cubic yard.

Units of Volume: U.S., Imperial, and Metric Measurements

A unit of volume is used to measure the volume or capacity of an object or enclosed space in three dimensions. 

To calculate the volume of a space, use this formula:

Volume = Length x Width x Height

For example, a 10-gallon aquarium would be 12 inches high, 20 inches long, and 10 inches wide. To determine its volume, multiply the length by the width and the height to get the cubic feet. Convert the inch value to feet first. For example, 20 inches would be 1.66666666667 feet.

Common units of volume include liters, cubic meters, cubic yards, pints, cups, and gallons. In most countries, they use metric units of volume, such as cubic millimeters, cubic centimeters, cubic decimeters, cubic meters, and cubic kilometers. 

In the U.S. and imperial systems, they use pints, cups, quarts, and gallons as units of volume. Although the imperial and U.S. systems of measuring volume use the same units, the imperial system’s units are larger, except for the fluid ounce.

• One cubic centimeter equals 0.0610237 cubic inches
• One cubic decimeter equals 1,000 cubic centimeters and 0.0353147 cubic feet.
• One cubic meter equals 1,000 cubic decimeters and 1.30795 cubic yards.
• One liter equals 1 cubic decimeter, 2.113 fluid pints, and 1.75975 pints.
• One fluid ounce equals 29.57 milliliters
• One cup equals 0.24 liters
• One pint equals 0.47 liters
• One gallon equals 3.79 liters
• One imperial fluid ounce equals 28.41 milliliters
• One imperial pint equals 0.57 liters
• One imperial quart equals 1.13 liters
• One imperial gallon equals 4.54 liters

Volume Measurements in Cannabis Cultivation

Cannabis growers must understand the different units of volume and how to convert one to another.

Here are a few instances that require knowing the volume of an area:

• Building a mezzanine if you have enough space to maximize your vertical garden space
• Determining the minimum air exchange needed in your grow room
• Determining how much soil to buy and put in pots
• Calculating the volume of raised garden beds
• Figuring out how much CO2 to add
• Making your own cannabis soil mix
• Managing water usage

What Is a Cubic Foot?

A cubic foot is a unit of volume used in the U.S.Customary and imperial measurement systems and is defined as “a unit of volume equal to a cube one foot long on each side.” A cubic foot equals 1,728 cubic centimeters, 28.317 liters, and roughly 0.028317 cubic meters.

The cubic foot volume unit is based on the foot, which is derived from the international yard. An international yard equals 0.9144 meters.

Cubic feet are common units of measurement in the United States and some parts of Canada and the United Kingdom. The more widely used metric system of measurement is also used in these countries.

What Is a Cubic Yard?

A cubic yard is a unit of volume in the US customary measurement system and is defined as “a unit of volume equal to a cube one yard long on each side.” A cubic yard equals 27 cubic feet, 764.5549 liters, and 0.7645549 cubic meters.

The cubic yard definition is derived from the international yard, introduced in 1959. The international yard equals 0.9144 meters.

The cubic yard is a common unit of volume in the US, Canada, and the UK, although they also use metric units of liters, milliliters, and cubic meters.

How to Measure Cubic Feet and Cubic Yards

Measuring volume is possible using numerous measuring tools or formulas. To determine the volume of solids, you can use their dimensions and plug them into the right volume equation. A graduated measuring tool can be used to measure a liquid’s volume. The containers used to measure volume differ if you’re in the kitchen or a chemistry lab.

Here is how to calculate the volume of different shapes:

• Cylinder: To find the cubic feet of a cylinder, you can multiply the height by its diameter and then multiply the result by pi (3.14).
• Cube: Calculate a cube’s volume by multiplying the length of the side 3 times.
• Sphere: A sphere’s volume is four-thirds multiplied by pi multiplied by the radius cubed.
• Cone: A cone’s volume is one-third the area of the base multiplied by the height.
• Pyramid: A pyramid’s volume is one-third the base’s area multiplied by the height.
• Box: Multiply the length by the width and the height.
