Examples

015 ml = 1.014421 tsp

Example value from the reference table. Internal calculation uses stored factors; display output is rounded.

02Common mistake

Volume is robust for liquids. For dry ingredients it does not replace weighing because density and packing vary.

03Base unit: l

1 ml = 0.001 l. Then the value is converted through the base unit l into Teaspoon.
