Cubic Inches to Cubic Yards (in³ to yd³)

1 cubic inch equals 0.00002143347051 cubic yards (rounded).

1 cubic inch = 0.00002143347051 cubic yards

How to convert cubic inches to cubic yards

To convert cubic inches to cubic yards, multiply the number of cubic inches by 0.00002143347051. The factor is rounded to 10 significant digits. To go the other way, multiply cubic yards by 46,656.

cubic yards = cubic inches × 0.00002143347051

Example: 10 cubic inches = 0.0002143347051 cubic yards.

Pints, quarts, gallons and fluid ounces differ between the US and the UK. Units are labeled 'US' or 'imperial' to avoid confusion.

About these units

Cubic Inch (in³)

US & ImperialCurrent unit

Exactly 16.387064 mL. Used for engine displacement in the US and for small mechanical parts.

Cubic inch is a unit defined by a ruler. Take an inch, build a cube, and its volume is exactly 16.387064 milliliters under the modern definition of the inch as 25.4 millimeters. Its main role in history is as the building block behind other US volumes: the US gallon is defined as 231 cubic inches, so a cubic inch is exactly 1/231 of a gallon. Even the 42-gallon oil barrel works out to precisely 9,702 of them.

The cubic inch survives most visibly in American engines, which are abbreviated c.i.d. for cubic inch displacement, while the rest of the world and many modern automakers speak in liters. A 5.7 liter engine is about 350 cubic inches, a conversion made easy by the exact factor of 16.387064. Small mechanical parts are also sized in cubic inches in North America.

1 cubic inch = 0.016387064 liters (exactly).

Cubic Yard (yd³)

US & ImperialCurrent unit

27 cubic feet or 764.555 liters. Used for soil, gravel and concrete in the US.

Cubic yard is a cube three feet on each side, which makes it exactly 27 cubic feet or 46,656 cubic inches. In metric terms it is about 0.7646 cubic meters, or 764.55 liters. The unit follows the yard in the United States and Canada, and British railways once rated ballast wagons by it, with one Great Western Railway wagon holding 8 cubic yards.

A cubic yard is easier to picture than the number suggests. It holds about 202 US gallons, or nearly five oil barrels. That is a scale where bulk materials such as soil, gravel, mulch and concrete are naturally counted, so a patio slab or garden bed needs a handful of them. A handy rule of thumb follows from the arithmetic: one cubic yard spread one inch deep covers 324 square feet.

1 cubic yard = 764.554858 liters (approximately).
