Oats: mL to Grams and Grams to mL
If a recipe lists rolled oats in mL and your scale reads grams, the short answer is that 100 mL of rolled oats weighs about 38 g. Rolled oats is lighter than water, so the two numbers are never the same.
The Formula
mL to grams: Weight (g) = Volume (mL) × 0.38
Grams to mL: Volume (mL) = Weight (g) ÷ 0.38
Worked Examples
- 15 mL of rolled oats = 5.7 g
- 250 mL of rolled oats = 95 g
- 200 g of rolled oats = 526.3 mL
Common Kitchen Measures
- 1 teaspoon (4.93 mL) = 1.9 g
- 1 tablespoon (14.79 mL) = 5.6 g
- 1/4 cup (59.1 mL) = 22.5 g
- 1/2 cup (118.3 mL) = 45 g
- 1 cup (236.6 mL) = 89.9 g
Why Rolled Oats Weighs What It Does
Rolled oats are flat flakes that stack loosely and leave a lot of air. A density of about 0.38 g per mL means a cup is only about 90 g.
Measuring Tips
Quick oats and steel cut oats pack differently, so the weight per cup changes. Use grams when the type matters.
