100 grams of honey in cups
Honey clings, so a cup of it is the worst measure in baking. On paper 100 grams is about 0.29 of a US cup, but the honey left coating the cup wall is the part your recipe never gets. Weigh it, or count tablespoons.
The cup you can't empty
Honey is heavy, 339 g to the cup, so 100 g is only 0.29 of one. The trouble is not the number, it is the pour. Honey coats whatever it touches, and a film clinging to the cup can be several grams you measured and never used. That is why King Arthur, which prints a cup for flour and sugar, publishes only a tablespoon for honey and stops there.
Weigh it, or count spoons
With no scale, the tablespoon beats the cup, because you scrape it flat and little stays behind. Both American authorities put a tablespoon of honey at 21 g, so 100 g is about 5 tablespoons. Warm the spoon or oil it and the honey slides off clean. One more wrinkle: set, crystallised honey packs heavier than liquid, so a granular jar reads a few grams more per spoon. The honey master page carries the tablespoon both authorities publish and the crystallised-versus-liquid gap.
Other honey weights in cups
The cup figures for common amounts, if you must pour:
| Honey | US cups |
|---|---|
| 50 g | 0.15 cups |
| 100 g | 0.29 cups |
| 150 g | 0.44 cups |
| 200 g | 0.59 cups |
| 250 g | 0.74 cups |
The same 100 grams runs the other way for light things. It is 1.1 cups of oats and a middling 0.41 of a cup of milk. Double it and 200 grams of honey is about three-fifths of a cup.
Common questions about honey by weight
- Is 100 grams of honey half a cup?
- No, closer to a third. 100 g of honey is about 0.29 of a US cup; a level half cup weighs about 170 g.
- How many tablespoons is 100 grams of honey?
- About 5, at 21 g to a level tablespoon, the figure both King Arthur and the USDA print. The spoon is the cleaner tool, since honey clings to a cup.
- Why is a cup of honey hard to measure?
- Honey coats the cup and a film stays behind, so what you pour out is less than what you measured. Warming or oiling the cup helps; a scale sidesteps it.
