To convert a measurement in yards to a measurement in millimeters, multiply the length by the following conversion ratio: 914.4 millimeters/yard.

Since one yard is equal to 914.4 millimeters, you can use this simple formula to convert:

millimeters = yards × 914.4

The length in millimeters is equal to the length in yards multiplied by 914.4.

For example, here's how to convert 5 yards to millimeters using the formula above.
millimeters = (5 yd × 914.4) = 4,572 mm

How Many Millimeters Are in a Yard?

Yards and millimeters are both units used to measure length. Keep reading to learn more about each unit of measure.

What Is a Yard?

The yard is a unit of length measurement equal to 3 feet or 36 inches. The international yard is legally defined to be equal to exactly 0.9144 meters.[1]

The yard is a US customary and imperial unit of length. Yards can be abbreviated as yd; for example, 1 yard can be written as 1 yd.

What Is a Millimeter?

One millimeter is equal to one-thousandth (1/1,000) of a meter, which is defined as the distance light travels in a vacuum in 1/299,792,458 of a second. One millimeter is equal to 0.0393701 inches.

The millimeter, or millimetre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "milli" is the prefix for thousandths, or 10-3. Millimeters can be abbreviated as mm; for example, 1 millimeter can be written as 1 mm.

Millimeters are often represented by the smallest ticks on most metric rulers. To get a reference point of the size, the thickness of a US dime is 1.35mm.[2]

We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or a combination of both values, so make sure you get the correct type for your needs.
