Cubic Meters to Metric Teaspoons (m³ to tsp)

1 cubic meter equals 200,000 metric teaspoons exactly.

1 cubic meter = 200,000 metric teaspoons

How to convert cubic meters to metric teaspoons

To convert cubic meters to metric teaspoons, multiply the number of cubic meters by 200,000. This factor is exact. To go the other way, multiply metric teaspoons by 0.000005.

metric teaspoons = cubic meters × 200,000

Example: 10 cubic meters = 2,000,000 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 Meter (m³)

Metric (SI)Current unit

The SI derived unit of volume: 1,000 liters. Used for water supply, gas, concrete and shipping space.

When the metric system was set up, the cube whose edge is one meter became its natural large unit of volume. A cubic meter also went by other names: kiloliter, now rarely used, and stere, still applied to stacked firewood. In modern SI it is the coherent derived unit of volume, and the liter is a convenience unit defined from it as one thousandth of a cubic meter.

A cubic meter is large by everyday standards. It holds 1,000 liters, and pure water at its densest weighs almost exactly one tonne in that space, which is how the metric tonne and the cubic meter ended up so conveniently paired. It is the unit of choice for water supply, gas, timber, concrete and shipping space, where freight is often quoted in CBM. For a picture, about 6.29 oil barrels or 264 US gallons fit in one, and an Olympic swimming pool, at least 2 meters deep, holds roughly 2,500 of them.

1 cubic meter = 1,000 liters (exactly).

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).
