About Converting Metric teaspoons to Metric cups
Metric teaspoon and Metric cup both show up in recipes, and converting between them matters whenever a recipe from one country's cookbook needs to be followed with another country's measuring tools. Specifically: A metric teaspoon is 5 milliliters, and a metric cup is 250 milliliters.
Formula
metric cups = metric teaspoons × 0.02
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 metric cup equals 0.00025 base units, so dividing one by the other gives the direct metric teaspoon-to-metric cup factor of 0.02.
Simple example
1 metric tsp × 0.02 = 0.02 metric cup
1 metric teaspoon = 0.02 metric cups.
Real-world example
2 metric tsp × 0.02 = 0.04 metric cup
2 metric teaspoons = 0.04 metric cups.
