## How to convert imperial units

There is no unique rule to convert between imperial units: unlike the metric system, where a division or multiplication by $10$ can bring you wherever you need, imperial units follow varying relationships, with ratios between multiples and submultiples often changing.

There's no solution or shortcut: you must remember all the conversions or use a tool to help you with that! In the following sections, you will learn how to do so for the most commonly measured quantities.

## Calculate imperial units of measurements conversions for the most common quantities

#### Converting imperial units of measurement for length

In the imperial system, we measure length using an assortment of units: **inches, feet, yards, and meters**. The "base" unit, the most commonly used, is the **foot**. Why foot? Because in the past, to define this unit, the body part of kings and rulers were used as standards! Feet are great for measuring "human-sized" objects. If you need to measure smaller objects, go for inches; for bigger things, use yards and miles. The relationships between these units are:

It may be helpful to know some of the inverse conversions:

#### Converting imperial area units of measurement

To convert area imperial measurement units, simply take the **square** of the conversion factors for length. For example:

#### Converting imperial volume units

You know how it works now! If we had to consider a square to learn the units for area, to find the units for the volume, we would have to **calculate the cube of the length's conversion factor**. The previous conversion becomes:

#### How to calculate and convert imperial units for weight

The most commonly used unit for weight in the imperial system is the **pound**. A pound is great for measuring your weight or the weight of an object you can lift with minimal effort. If you don't even feel the weight, you should use the **ounces** ($\mathrm{oz}$). For objects you can't lift unless you are a superhuman, you should use the **ton**. Here are the conversion factors:

#### Temperature conversion in the imperial system

There are only **two temperature units** in the imperial system: the **Fahrenheit** and the **Rankine**. The first one is perfect for measuring the temperature of the day; the other can be used by scientists, as it assigns the **zero point** to the **absolute zero**. We convert between these two units with a simple sum/subtraction:

You can use our imperial calculator to convert between units! However, if you want to do these operations on your own, here is a collection of tables to sum up the conversions we detailed above.

$\mathrm{in}$ | $\mathrm{ft}$ | $\mathrm{yd}$ | $\mathrm{mi}$ | |
---|---|---|---|---|

$\mathrm{in}$ | — | $0.08333$ | $0.02778$ | $0.000015783$ |

## FAQ

### How do I calculate and convert imperial units for length, area, and volume?

To calculate the conversion of imperial units for length, area and volume, follow these simple steps:

- Remember the conversion of imperial units for the length:
`1 mi = 1,760 yd`

`1 yd = 3 ft`

;`1 ft = 12 in`

- To convert between surface imperial measurement units, use the
**square**of the corresponding conversion factors for length (for example,`1 ft² = 144 in²`

). - The conversion of volume imperial measurement units uses the
**cube**of the conversion factors for the length (that is,`1 ft³ = 1,728 in³`

).

### How much is 10 inches in feet?

`10`

inches is `0.8333`

feet. To find this result, follow these easy steps:

- Find the conversion between inches and feet:

`1 in = 0.08333 ft`

- Multiply the conversion factor by the quantity you need to convert:

`10 in = 10 × 0.08333 ft = 0.8333 ft`

That's it!

### How do I convert cubic feet to gallons?

Gallons and cubic feet are both units of volume in the imperial system. To convert between them, use the following conversion:

`1 ft³ = 7.48 gal`

The inverse conversion is:

`1 gal = 0.13368 ft³`

This conversion can help you switch from cubic feet, inches, and yards to gallons, pints, and cups.

### How do I convert imperial units?

To convert imperial units, you need to learn the conversion factors between them. Here are some of them:

- Length:
`1 yd = 3 ft`

and`1 ft = 12 in`

; - Area:
`1 yd² = 9 ft²`

and`1 ft² = 144 in²`

; - Volume:
`1 yd³ = 27 ft³`

and`1 ft³ = 1728 in³`

; - Weight:
`1 lb = 16 oz`

and`1 ton = 2000 lb`

.

By multiplying conversion factors, you can find how to pass from any units associated with the same quantity.
