Measuring Tip
Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.
Understanding the Units
What is a Teaspoon?
A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.
What is an Ounce?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.

The most accurate way is to weigh water on a kitchen scale. If you are measuring by volume, use a liquid measuring spoon on a flat surface and read the level at eye height. Liquids settle naturally, so volume measurements are already quite consistent.
Very close. Pure liquid densities are consistent across brands, so the teaspoons to ounces conversion for water typically varies by less than 2-3%.
For liquids like water, volume measurements are already quite accurate since liquids settle to a consistent level. A kitchen scale adds precision but the difference is typically small for liquid ingredients.
