150 Grams of Oats to Cups
1⅔ cups in a US cup — and what that looks like with a measuring spoon
150 grams of rolled oats is 1⅔ cups in a US cup. In the kitchen that is 1½ cups, 2 tablespoons plus 2 teaspoons.
Grams weigh and cups fill, so the answer only exists once you say what is in the cup. A US cup of rolled oats weighs 90 g, and every figure on this page comes from that one number.
It also depends on whose cup you mean. In a 250 ml metric cup — the standard in the UK, Australia, New Zealand and Canada — 150 g of rolled oats is 1⅝ cups, because that cup holds about 5.7% more than the 236.6 ml US cup.
Round to the nearest measure in a standard cup set — 1¾ cups — and you are 8 g over, about 5% of the amount.
150 g of oats in each cup standard
| Cup standard | Size | Grams per cup | Cups |
|---|---|---|---|
| US customary | 236.6 ml | 90 g | 1⅔ |
| Metric (UK, AU, NZ, CA) | 250 ml | 95 g | 1⅝ |
| Imperial (older UK) | 284 ml | 108 g | 1⅜ |
A recipe that says "cups" without saying which one is almost always American. If it came from a British, Australian or New Zealand source, use the metric row.
How to measure 150 g of oats without scales
Rolled oats are light and airy. Spoon them into the cup and level it — pressing them down can add 15 g or more to a cup.
These are old-fashioned rolled oats at 90 g per cup. Quick oats are cut smaller and settle to 85 g, and steel-cut oats are much denser at 160 g.
- Build it as 1½ cups, 2 tablespoons plus 2 teaspoons rather than guessing at 1⅔ of a cup.
- 150 g is 26.67 tablespoons of rolled oats, at 5.63 g per tablespoon.
- A digital scale removes the question entirely, and costs less than the ingredients it saves.
