The imperial system is sort of random in comparison to the metric system. There are 5,280 feet in a mile, 3 feet to a yard, and 12 inches in a foot. So, if you come across a measurement in inches, how do you get the measurement in feet?

**To convert inches to feet, divide the number of inches by 12. For example, if you have 36 inches, then 36 inches / 12 = 3 feet. To convert feet to inches, multiply the number of feet by 12. So, if you have 3 feet, then 3 feet x 12 = 36 inches.**

In this guide, I’ll explain the somewhat random history of the inch and feet, as well as how to convert inches to feet (and vice versa).

**History of the Inch and Foot**

In both the British Imperial and American Customary systems, the inch is used as a unit of measurement. The word “ince” or “ynce,” which means 1/36 of a yard, originates from the Latin word “uncia,” which means “one-twelfth” of a Roman foot.

In the past, the inch was defined by the width of a man’s thumb at the nail’s base; measurements were typically taken from the thumbs of three men of varying sizes and then divided by three to ensure consistency. Historically, 12 poppy seeds or 3 grains of barley were used to establish the length of an inch.

The foot, based on the length of a person’s foot, is a linear unit of measurement used primarily in English-speaking countries. One-third of a yard, or 12 inches, is the standard length. The meter, the fundamental linear unit of the metric system, has largely succeeded the foot as the standard length measurement in most countries and scientific contexts. It wasn’t until 1959 that the inch was defined as 2.54 centimeters and that the foot was officially defined as 30.48 centimeters.

**Inch to Foot Conversion**

Converting feet to inches is pretty simple business. All you have to do is divide the figure in inches by 12 to get its measurement in feet. Getting inches from feet is pretty simple, as well, as long as you remember that there are 12 inches to every foot!

**How Many Cubic Inches Are In a Yard?**

A yard, in gardening and construction terms, is a cubic yard. We know that a yard is equal to 3 feet, so a cubic yard would equal 27 cubic feet (3 × 3 × 3 feet). Now, how do we convert this into cubic inches?

A cubic foot is equal to 1,728 cubic inches (12 × 12 × 12 inches). All we have to do is multiply that by 27, and we’ll get a total of 46,656 cubic inches per cubic yard.

**How Many Square Inches Are in an Acre?**

An acre is a unit of land measurement that is commonly used in the United States and the United Kingdom. It is equal to 43,560 square feet.

Knowing this, all we have to do is multiply 43,560 by 12 inches and again by 12 inches. This will give us a figure of 6,272,640 square inches.

**How Many Square Inches in a Hectare?**

A hectare (abbreviated “ha”) is a unit of area measurement that is commonly used in the metric system. It is equal to 10,000 square meters.

First, let’s calculate how many square inches are in a square meter. A square meter is 100 centimeters by 100 centimeters, so that would give us 39.37 × 39.37 inches or 1,549.9969 square inches per square meter.

All that’s left to do is to multiply that figure by 10,000 to get the number of square inches in a hectare. The product would be 15,499,969 square inches.
