160 Grams of Powdered Sugar in Cups
160 grams of powdered sugar doesn't land on a clean fraction, so the result below is calculated exactly rather than rounded to a common measure. Based on a density of 120g per cup, it equals 1.33 cups.

- 1.33 (1⅓)

160 grams of powdered sugar = 1.33 cups (1⅓ cup / 21.3 tbsp / 64.0 tsp)
Powdered Sugar has a density of approximately 120g per cup. Sifted: 100g. Unsifted and packed: up to 130g. 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.
| Grams | Cups | Fraction | Tablespoons | Teaspoons |
|---|---|---|---|---|
| 140g | 1.17 | 1⅛ | 18.7 | 56.0 |
| 150g | 1.25 | 1¼ | 20.0 | 60.0 |
| 160g | 1.33 | 1⅓ | 21.3 | 64.0 |
| 170g | 1.42 | 1⅜ | 22.7 | 68.0 |
| 175g | 1.46 | 1½ | 23.3 | 70.0 |
How 160g Converts, Step by Step
160g divided by 120g (the weight of one cup of powdered sugar) equals 1.33 cups. Multiplying that by 16 gives 21.3 tablespoons, and by 48 gives 64.0 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Powdered Sugar is lighter than water, which weighs about 236g per cup. That's why 160g of powdered sugar takes up more volume (315ml) than the same weight of water would (160ml). For a side-by-side look at how other ingredients compare, see the 160 grams to cups page.
If You're Using a Metric or Imperial Cup
The 1.33 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 160g, that's 1¼ metric cups or 1⅛ imperial cups of powdered sugar, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.
Scaling This 160g Amount
Doubling a recipe that calls for 160g of powdered sugar means weighing 320g, or measuring 2.67 cups if you're working by volume instead of weight. Halving it means 80g, or 0.67 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.
Powdered Sugar Next to Other Sugars & Sweeteners
Within sugars & sweeteners, density still varies by ingredient. At 160g, granulated sugar (200g per cup) measures ¾ cup, while brown sugar (220g per cup) measures ¾ cup, compared to 1⅓ cup for powdered sugar. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Where This Amount Shows Up in Recipes
- A basic buttercream frosting typically uses 400g to 500g of powdered sugar.
- Glazes for donuts or scones often call for 120g.
- Dusting a finished cake usually takes just 15g to 30g.
Measuring This Precisely
Sugars & Sweeteners
Granulated sugar should be spooned and leveled. Brown sugar should be pressed firmly until it holds the cup's shape when turned out.
For exact results
Powdered sugar clumps easily during storage, so sifting it before measuring gives a more consistent, lump-free result. Liquid sweeteners like honey and maple syrup should be measured in a liquid cup and poured slowly to avoid trapping air bubbles.

Frequently Asked Questions
What is 160 grams of powdered sugar in cups exactly?+
160 grams of powdered sugar equals 1.33 cups, based on a density of 120g per cup.
Why doesn't 160g of powdered sugar match a simple fraction?+
160g isn't a multiple of powdered sugar's per-cup weight, so the cup value lands between common fractions. The closest practical measure is 1⅓ cup.
What's the most reliable way to measure 160g of powdered sugar?+
A kitchen scale set to grams gives an exact 160g reading. Cups only approximate this amount, since 1⅓ cup rounds to the nearest practical fraction.
Is 160g likely a typo for a rounder amount?+
Possibly, if a recipe seems to expect a cleaner number. Check the nearby amounts table below for the closest common gram values for powdered sugar.
