How to convert metric cups to cubic yards

To convert metric cups to cubic yards, multiply the number of metric cups by 0.0003269876548. The factor is rounded to 10 significant digits. To go the other way, multiply cubic yards by 3,058.219432 (rounded).

cubic yards = metric cups × 0.0003269876548

Example: 10 metric cups = 0.003269876548 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

Metric Cup (cup)

Cooking & barCurrent unit

Exactly 250 mL. The cup used in Australia, New Zealand and most Commonwealth recipes.

A metric cup is a cup tamed by decimal thinking. Australia, Canada, New Zealand and some other former British colonies that metricated use a round 250 milliliters, exactly a quarter of a liter. Canada's older cup had been eight imperial fluid ounces, about 227.3 mL, so the metric version is noticeably larger, and Canadian recipes now usually use the 250 mL cup.

The metric cup is not an SI unit, only a practical convention, and it differs from the US cups in useful ways. It is about 6 percent larger than the US customary cup at 236.6 mL and about 4 percent larger than the 240 mL US label cup. Its arithmetic is simple: four cups make a liter, and a cup holds 50 metric teaspoons or 16 and two thirds tablespoons of 15 mL. Many recipes outside the US skip cups entirely and give dry ingredients in grams, because volume is a rough proxy for flour.

1 metric cup = 0.25 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).
