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?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
