Milliliter to Teaspoon Converter

Convert milliliters to teaspoons instantly. Free, bidirectional, and fully in-browser.

1 milliliter equals 0.2028841362 teaspoons — enter any milliliter value to convert it to teaspoons instantly.

A reference table lists common milliliter values already converted, and nothing you enter is sent to a server.
