About Converting Cubic Millimeters to Metric teaspoons
Cubic Millimeter and Metric teaspoon appear side by side at fuel pumps and on beverage labels, since the US measures liquids in gallons while most of the world uses liters. Specifically: Cubic metric volume unit, and a metric teaspoon is 5 milliliters.
Formula
metric teaspoons = cubic millimeters × 0.0002
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter equals 1e-9 base units, and 1 metric teaspoon equals 0.000005 base units, so dividing one by the other gives the direct cubic millimeter-to-metric teaspoon factor of 0.0002.
Simple example
1 mm3 × 0.0002 = 0.0002 metric tsp
1 cubic millimeter = 0.0002 metric teaspoons.
Real-world example
10 mm3 × 0.0002 = 0.002 metric tsp
10 cubic millimeters = 0.002 metric teaspoons.
