Cubic Feet

Estimating the precise volume of spaces or objects can be a challenge, particularly when planning to move, ship goods, or calculate storage. The Cubic Feet Calculator emerges as a valuable tool for such tasks.

This guide introduces an effortless way to determine spatial requirements using our user-friendly cubic feet calculator. Discover accurate measurements with simplicity—continue reading for essential insights.

What is the Cubic Feet Calculator?

A Cubic Feet Calculator is a tool that helps you figure out the volume of space inside a box or other shape. You just put in the length, width, and height of your box and choose what unit you’re measuring in, like inches or meters.

Then, with one click on “calculate,” it tells you how many cubic feet are there.

This calculator can be really helpful for lots of things. Let’s say you want to ship something and need to know if it will fit in a truck. Or maybe you’re buying soil for your garden and need to find out how much to get.

With this calculator, making those kinds of guesses becomes super easy. Now let’s learn about the formulas that make this all work! You can also Calculate the volume, surface area, and other properties of a sphere with our comprehensive Sphere Calculator.

Formulas to Calculate Cubic Feet

Understanding the formulas to calculate cubic feet is essential for a myriad of practical applications, from determining shipping costs for less than truckload (LTL) freight to measuring the volume required for materials like concrete.

This section will provide clear instructions and conversions necessary to efficiently convert dimensions into cubic feet, ensuring accuracy whether you are working with simple rectangular shapes or converting units of measure from meters, yards, or inches.

Volume of a Cube

To find out how much space is inside a cube, you need to know its volume. You can get this number by multiplying the length of one side three times. If all sides are the same size and you call that size the length “L,” your formula looks like this: Volume = L * L * L.

Imagine you have a toy block that is 2 feet long on each side. To calculate the volume in cubic feet, use your formula: 2 ft. * 2 ft. * 2 ft., which equals 8 cubic feet. This tells us our block has an inside space of 8 cubic feet.

It’s simple multiplication and helps you understand how big something is!

Conversions from Meters, Yards, and Inches

Changing meters, yards, and inches into cubic feet is easy. Our calculator helps you do this quickly.

  • Start with your measurements in meters. To change them to cubic feet, multiply by 35.31.
  • For example, if you have a box that is 1 meter long, 1 meter wide, and 1 meter tall, the formula looks like this: Volume = 1m * 1m * 1m. Next, turn meters cubed into cubic feet: Volume(ft^3) = 1m^3 * 35.31 = 35.31ft^3.
  • If your measurements are in yards, convert them to cubic feet differently.
  • Use this formula for yards: Volume = Length(yard) * Width(yard) * Height(yard).
  • To turn that volume into cubic feet, remember that one yard equals three feet.
  • So for a space measuring one yard by one yard by one yard, you’d calculate: Volume(yard^3) = 1yd * 1yd * 1yd = 27 because there are three feet in a yard and we cube it (3*3*3).
  • Now let’s talk about inches. You might measure small boxes or spaces in inches.
  • The formula to go from inches to cubic feet is also simple.
  • You just use the length in inches times width in inches times height in inches.
  • After getting the total volume in cubic inches, divide by the number of cubic inches in a foot.
  • There are exactly twelve inches in a foot and thus we have: Volume(inches^3) = Length(in) * Width(in) * Height(in).
  • Divide it by how many cubic inches are in a cubic foot — which is \(12\text{in} \times12\text{in} \times12\text{in}\), or \(1728\text{cubic inches}\).

How to use the cubic feet calculator (step-by-step information)

Using our Cubic Feet Calculator is easy and helpful. It helps you find out how much space something takes up.

  • First, look at what you want to measure. Maybe it’s a box or a room.
  • You need three numbers: the length, width, and height of your space.
  • Start with measuring the length. Use a ruler or tape measure and write down the size.
  • Next, measure how wide the space is. Write this number down too.
  • Last, find out how tall the space is from top to bottom and note that number.
  • Open the Cubic Feet Calculator on your computer or phone.
  • Type your length number into the first box on the calculator.
  • Now enter your width number into the second box.
  • Put your height number into the third box on the screen.
  • Pick what units you are using from a drop-down menu. You can choose inches, feet, yards, millimeters, centimeters, or meters.
  • Click or tap on “calculate.” The calculator will work its magic!
  • You’ll see how many cubic feet your space is. This tells you its volume.

Examples of calculations with cubic feet calculator

Certainly! Below is an example of a simple table where you can see the results obtained from the Cubic Feet Calculator for different dimensions:

Length (ft) Width (ft) Height (ft) Cubic Feet
5 3 2.5 37.5
8 4 3 96
10 6 4 240
12 8 5 480

Cubic Feet of Irregular Shapes

Measuring funny-shaped things can seem hard. But our calculator makes it easier. To find out how many cubic feet are in an odd shape, think of the shape as smaller boxes or other shapes you know—like cubes and rectangles.

Measure these parts one by one. Put the length, width, and height for each part into the calculator. Choose inches, feet, yards, millimeters, centimeters, or meters from a list.

Add up all the small shapes’ volumes to get the total volume for your weird shape. This way helps you see how much space that shape takes up in cubic feet. People use this method for packing stuff, building things, and when they need to fill spaces smartly.

Now let’s look at why knowing about cubic feet is important!

Are Feet and Cubic Feet the Same?

Feet and cubic feet are not the same. A foot is a unit that measures how long or wide something is. It tells us the distance from one point to another. Cubic feet, on the other hand, measure volume.

This means it tells us how much space something takes up in three dimensions – length, width, and height combined.

Imagine you have a box. If you use a single foot to measure one side of this box, that’s just a straight line from one corner to another. But when you fill that box with water or anything else, we say its volume is so many cubic feet because we’ve considered all parts of it – top to bottom, front to back, side to side.

That’s the big difference: feet for length and cubic feet for full space inside an object. If you need to convert volumes to cubic meters? Our Cubic Meter Calculator is here to help

Cubic Foot to Other Units Conversion
