150 grams of water = 0.64 cups (⅝ cup / 10.2 tbsp / 30.5 tsp)

Water has a density of approximately 236g per cup. The baseline liquid density — 236.588g per cup at standard kitchen temperature. Source: USDA / NIST. 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 236g (the weight of one cup of water) equals 0.64 cups. Multiplying that by 16 gives 10.2 tablespoons, and by 48 gives 30.5 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.

Water is close to water in density, so 150g fills a similar volume (150ml) to the same weight of water. 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 0.64 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 ⅝ metric cups or ½ imperial cups of water, 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 water means weighing 300g, or measuring 1.27 cups if you're working by volume instead of weight. Halving it means 75g, or 0.32 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.

Water vs. Other Liquids

Within liquids, density still varies by ingredient. At 150g, vanilla extract (208g per cup) measures ¾ cup, compared to ⅝ cup for water. 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 water in cups?+

150 grams of water is 0.64 cups (⅝ cup), or 10.2 tablespoons.

How do I measure 150 grams of water without a scale?+

Use ⅝ cup, spooned in and leveled off with a straight edge. If you only have tablespoons, use 10.2 tablespoons instead.

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

Water weighs 236g per cup because of its own density. The baseline liquid density — 236.588g per cup at standard kitchen temperature.

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

Yes, slightly. 150g of water is ⅝ metric cups or ½ imperial cups, versus ⅝ US cups, since each cup standard holds a different volume.
