How Much Is 4 Teaspoons of Brown Sugar in Ounces?

4 teaspoons of brown sugar weighs 0.65 oz. This is based on brown sugar having a density of 220g per cup. Because teaspoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 4 teaspoons.

Formula and Step-by-Step

teaspoons × 4.58g/tsp ÷ 28.3495g/oz = ounces
  1. Start with 4 teaspoons of brown sugar
  2. 1 teaspoon of brown sugar = 4.58g
  3. 4 × 4.58 = 18.33g
  4. Convert grams to ounces: 18.33 ÷ 28.3495 = 0.65 oz

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

If your brown sugar has hardened, microwave it with a damp paper towel for 20 seconds. Hard brown sugar is still the same weight but impossible to measure by volume.

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.
