150 grams of oat flour = 1.63 cups (1⅝ cup / 26.1 tbsp / 78.3 tsp)

Oat Flour has a density of approximately 92g per cup. Homemade (blended from oats) can run closer to 100g. Source: USDA FoodData Central. This is the figure used everywhere on this page, including the tablespoon and teaspoon values, so the numbers stay consistent whether you're reading the summary line, the table, or the FAQ answers below.

How the 150g Figure Is Calculated

cups = grams ÷ grams per cup

150g divided by 92g (the weight of one cup of oat flour) equals 1.63 cups. Multiplying that by 16 gives 26.1 tablespoons, and by 48 gives 78.3 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.

Oat Flour is lighter than water, which weighs about 236g per cup. That's why 150g of oat flour takes up more volume (386ml) than the same weight of water would (150ml). For a side-by-side look at how other ingredients compare, see the 150 grams to cups page.

If Your Recipe Uses Metric or Imperial Cups

The 1.63 cup figure above uses the US Customary cup (236.588ml). Recipes written outside the US sometimes use a metric cup (250ml) or an imperial (uk) cup (284.131ml) instead. At 150g, that's 1½ metric cups or 1⅜ imperial cups of oat flour, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.

Scaling 150g Up or Down

Doubling a recipe that calls for 150g of oat flour means weighing 300g, or measuring 3.26 cups if you're working by volume instead of weight. Halving it means 75g, or 0.82 cups. Weight scales exactly with simple multiplication; cup measurements compound any scooping error each time they're doubled or halved, so weighing is more reliable the more a recipe is scaled.

Oat Flour vs. Other Flours

Within flours, density still varies by ingredient. At 150g, almond flour (96g per cup) measures 1½ cup, while coconut flour (112g per cup) measures 1⅓ cup, compared to 1⅝ cup for oat flour. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.

Frequently Asked Questions

What is 150 grams of oat flour in cups?+

Why is oat flour's gram-to-cup ratio different from other ingredients?+

Oat Flour weighs 92g per cup because of its own density. Homemade (blended from oats) can run closer to 100g.

Does a metric or imperial cup change this 150g conversion?+

Yes, slightly. 150g of oat flour is 1½ metric cups or 1⅜ imperial cups, versus 1⅝ US cups, since each cup standard holds a different volume.
