Cups of honey to grams

What the sources say about a cup of honey

Two published sources, side by side. Where a source lists several forms or ways of measuring, each is a row.

Spread across sources: 1% between USDA and King Arthur for the main entry. Ingredient weights vary by brand, packing and humidity; the table is a reference, not a guarantee.

Why this number: 339 g per US cup

We use the USDA measured weight, because for liquids, fats, syrups and free-flowing grains a measured weight is more reliable than a rounded ounce value. Where the two sources disagree, both figures are in the table above and in the calculator, so you can switch to the one your recipe was written with.

Honey is about 1.43 times as heavy as water for the same volume, so a cup weighs 339 g, not the 237 g a cup of water does. USDA lists 339 g per cup and 21 g per tablespoon, and King Arthur also lists 21 g per tablespoon, which scales to 336 g a cup. Both agree.

The practical issue with honey is not the conversion but getting it out of the cup: it clings, so a volume measure always leaves some behind. Weigh the honey directly into the mixing bowl on a scale and the problem disappears.

A metric cup (250 ml) holds about 358 g of honey. For recipes that swap honey for sugar, the weights are not equal either: a cup of sugar is 200 g, a cup of honey is 339 g.

Grams of honey to cups

US cup, metric cup and spoons

One US cup of honey at our default weight is 339 g. A 250 ml metric cup, used in Australia, New Zealand, Canada and many metric recipes, holds the same volume plus 5.7%, which is 358 g. A US legal (nutrition label) cup of 240 ml is 344 g. These all assume the same packing as the US cup; read about it on US cup vs metric cup.

Sources and when they were checked

• USDA FoodData Central, SR Legacy (April 2018 release), food Honey (FDC ID 169640). Gram weights per household measure as published; per-cup figures where USDA lists a different amount (such as 2 tablespoons) are scaled.
• King Arthur Baking, Ingredient Weight Chart, row(s): Honey. Chart rows that list a quarter cup, half cup or tablespoon are scaled to a full cup on this page; the original listing is shown in the table above.
• Cup volumes: the US customary cup is exactly 236.5882365 ml; the US nutrition-label cup is defined in US law as 240 ml (21 CFR 101.9); the metric cup is 250 ml (see US cup vs metric cup).

Last checked 27 October 2026. Weights are for reference: ingredients vary by brand, humidity and how they are packed. If your recipe gives gram weights, use those.
