About Converting Metric teaspoons to Cubic Decimeters
Metric teaspoon and Cubic Decimeter 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: A metric teaspoon is 5 milliliters, and cubic metric volume unit.
Formula
cubic decimeters = metric teaspoons × 0.005
This factor comes from each unit's defined relationship to the category's base unit: 1 metric teaspoon equals 0.000005 base units, and 1 cubic decimeter equals 0.001 base units, so dividing one by the other gives the direct metric teaspoon-to-cubic decimeter factor of 0.005.
Simple example
1 metric tsp × 0.005 = 0.005 dm3
1 metric teaspoon = 0.005 cubic decimeters.
Real-world example
10 metric tsp × 0.005 = 0.05 dm3
10 metric teaspoons = 0.05 cubic decimeters.
