How many cups is 100 grams of ketchup?

One hundred grams of ketchup is about 0.37 cups, or roughly 5.9 tablespoons, using the standard 270 g per cup density.

How many tablespoons is 50 grams of ketchup?

Fifty grams of ketchup equals approximately 3 tablespoons. One tablespoon of ketchup weighs about 16.9 grams at 270 g per cup.

What density does this converter use for ketchup?

This converter uses 270 grams per US cup, the standard reference density for tomato ketchup used across recipe and nutrition sources. It is denser than water because of the tomato solids and sugar content.

Why is ketchup denser than water?

Ketchup concentrates tomato solids, sugar, and vinegar into a thick paste, which packs more mass into the same volume than plain water. Using the water figure (236 g per cup) would understate ketchup weight by roughly 15%.

Does the conversion change between ketchup brands?

Slightly. Thicker, sugar-heavy ketchups run a bit denser, while thinner or vinegar-forward styles run a bit lighter. 270 g per cup is a reliable average for standard bottled ketchup.

How do I convert the other way, from cups to grams?

Use the companion Ketchup Cups to Grams tool, which applies the same 270 g per cup density in reverse.

Quick-Reference Conversion Table

All values use 270 g = 1 US cup of ketchup.

Grams	Cups	Tablespoons	Ounces
17 g	1/16 cup	1 tbsp	0.60 oz
34 g	1/8 cup	2 tbsp	1.20 oz
50 g	0.19 cup	2.96 tbsp	1.76 oz
68 g	1/4 cup	4 tbsp	2.40 oz
100 g	0.37 cup	5.93 tbsp	3.53 oz
135 g	1/2 cup	8 tbsp	4.76 oz
200 g	0.74 cup	11.85 tbsp	7.06 oz
270 g	1 cup	16 tbsp	9.52 oz
500 g	1.85 cups	29.63 tbsp	17.64 oz

Values are measured by US cup (236.6 ml) using a density of 270 grams per cup of standard ketchup. This is an approximation; brand thickness and sugar content shift the real weight slightly.

Summary

Ketchup is thicker than water, so a gram figure on a nutrition label or bulk order sheet does not map directly to a measuring cup. This tool converts ketchup weight in grams to cups, tablespoons, and teaspoons using a density of 270 grams per US cup, the standard reference figure for tomato ketchup, and includes ounces and a quick reference table so you can check common amounts without doing the math.
