How Much Is 4 Teaspoons of Buttermilk in Ounces?
4 teaspoons of buttermilk equals 0.72 oz. Buttermilk has a density of 245g per cup (5.10g per teaspoon), which means it's relatively light compared to other common cooking ingredients. For comparison, 4 teaspoons of honey would be 1.00 oz.
Formula and Step-by-Step
- Start with 4 teaspoons of buttermilk
- 1 teaspoon of buttermilk = 5.10g
- 4 × 5.10 = 20.42g
- Convert grams to ounces: 20.42 ÷ 28.3495 = 0.72 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
