How to convert cubic yards to metric teaspoons

To convert cubic yards to metric teaspoons, multiply the number of cubic yards by 152,910.9716. The factor is rounded to 10 significant digits. To go the other way, multiply metric teaspoons by 0.000006539753097 (rounded).

metric teaspoons = cubic yards × 152,910.9716

Example: 10 cubic yards = 1,529,109.716 metric teaspoons.

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 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).

Metric Teaspoon (tsp)

Cooking & barCurrent unit

Exactly 5 mL, used in most countries.

Five milliliters is the metric teaspoon, a figure so tidy that it has become the working definition for medicine and food labels. The traditional British teaspoon was an imperial fluid drachm, one eighth of an imperial fluid ounce, about 3.55 milliliters, and the American one was 4.93 mL. US nutrition labeling law now defines a teaspoon as exactly 5 milliliters.

The 5 mL teaspoon matters most when dosing medicine. Kitchen spoons vary widely, with one Greek survey of 71 household teaspoons finding volumes from 2.5 to 7.3 mL, so measuring spoons, syringes and calibrated cups are the safer tools. It also anchors the metric cooking system: three teaspoons make a 15 mL tablespoon, and fifty fit in a 250 mL metric cup. Australia keeps a 5 mL teaspoon but counts four of them in its larger 20 mL tablespoon.

1 metric teaspoon = 0.005 liters (exactly).
