Units of Length in Metric and U.S Customary Systems

Length refers to a unit of length or the distance from one point to another. In the U.S. customary system of measurement, the basic units for length are inches, feet, yards, and miles. In the metric system of measurement, the basic units of length are millimeters, centimeters, meters, and kilometers.

Centimeters and millimeters are used to measure small lengths, while meters and kilometers are used for larger lengths and long distances. Decameter, hectometer, and kilometers are multiples of meters.

For instance, the length of a paper clip would be measured in centimeters while kilometers are used to measure the length between your home and your work.

Here is a list of standard metric length units:

• 1 millimeter equals 0.1 centimeters
• 1 centimeter equals 10 millimeters
• 1 meter equals 100 millimeters (100 centimeters and 10 decimeters)
• 1 decameter equals 10 meters
• 1 hectometer equals 100 meters
• 1 kilometer equals 1,000 meters

In the United States, we use the U.S. customary system units that include inches, feet, yards, and miles to measure length. These are also used in the imperial system of measurement. Inches and feet are used to measure smaller objects, while yards and miles are used to measure longer distances and lengths.

Here is a breakdown of the U.S. customary units of length:

• One foot equals 12 inches
• One yard equals 3 feet (36 inches)
• One mile equals 5,280 feet (1,760 yards)

What Is an Inch?

An inch (in) is a unit of length in the U.S. and imperial measurement systems. In 1959, the definition of an inch became 25.4 millimeters. An inch is 1/12 of a foot or 1/36 of one yard. There are 36 inches in a yard and twelve inches in a foot.

According to Merriam-Webster, an inch is defined as “a unit of length equal to 1/36 yard” and “a small amount, distance, or degree.” It can also be used to refer to “a fall (as of rain or snow) sufficient to cover a surface or to fill a gauge to the depth of 1 inch.”

An inch is also defined as “a degree of atmospheric or other pressure sufficient to balance the weight of a column of liquid (such as mercury) an inch high in a barometer or manometer.”

The term inch is derived from uncia, the Roman term for 1/12 of a foot. Early definitions of an inch have been based on the width of the human thumb and three grains of dry barley. Today, the inch is commonly used in the U.S., United Kingdom, and Canada. 

What Is a Foot?

A foot (ft) is a unit of length used in the imperial and U.S. customary measurement systems. In 1959, the foot’s definition was set to 0.3048 meters (304.8 mm). One yard is equal to three feet.

According to Merriam-Webster, a foot is defined as “any of various units of length based on the length of the human foot, especially a unit equal to ⅓ yard and comprising 12 inches – plural foot used between a number and a noun.” 

Before its current definition, the foot as a unit of measurement was used in various systems, including the French, Greek, Chinese, and Roman systems. Since these systems had different lengths of feet, the measurement of a foot varied between 250-335 millimeters.

Feet is a common unit of measurement used to measure a person’s height or short distances. It is also used in the aviation industry to measure altitude and elevation.

How to Measure Length in Feet and Inches

Measuring the length of an object can be accomplished with measuring tools like a ruler, yardstick, meter stick, or measuring tape. A ruler can be used to measure small objects like a pencil. A measuring tape can be used to measure larger objects like a person’s height.

Rulers are 12 inches (30.48 cm) long. Yardsticks are 3 feet (36 inches) long. Meter sticks are 1 meter (100 cm) long.

When using a ruler or measuring tape to measure length, you will notice that it has two sides listing centimeters and millimeters on one side and inches on the other. Choose the desired unit of length first. Then, you can place the object next to the ruler or measuring tape starting at the 0 mark. 

Measuring tools feature tick marks that allow you to see an object's length. Mark the tick mark closest to the object’s endpoint. That is the length. If the object falls between two tick marks, round to the lowest unit.
