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?

Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.

Frequently Asked Questions

About 12.83 oz, based on all-purpose flour having a density of 125.16g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 2.61 (grams per teaspoon for all-purpose flour), then divide by 28.3495 to convert grams to ounces. For 139.53 teaspoons: 139.53 × 2.61 = 363.82g, then 363.82 ÷ 28.3495 = 12.83 oz.
For the most accurate results, weigh all-purpose flour on a kitchen scale. If measuring by volume, sift or whisk first to break up clumps, then spoon into the measuring spoon and level off. Do not scoop directly from the bag.
Yes, quite a bit. If you spoon the flour into your measuring spoon and level it off, you will get about 125.16 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 137.68 to 156.45 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
