One U.S. cup of honey weighs about 339–340 grams; thickness and temperature can nudge the number a few grams.
Bakers, tea lovers, and recipe developers ask this all the time because honey is heavy for its volume and tough to scoop cleanly. You’ll get the most reliable results when you measure by weight, not volume. Below you’ll find the exact gram ranges for a cup of honey, why those grams can shift a little, and quick tables to convert cups, tablespoons, and different cup systems without fuss.
How Many Grams Are In 1 Cup Of Honey? By System
For the standard U.S. cup used in kitchens, one cup of honey comes in at roughly 339–340 g. This aligns with the serving selector on MyFoodData’s honey entry, which lists “1 cup (339 g)”. Food labeling in the U.S. also defines a “cup” as 240 mL, a helpful anchor when you’re converting sticky ingredients to grams (21 CFR 101.9).
Different “cups” exist worldwide, and honey’s density makes those differences matter. As a rule of thumb:
- U.S. customary cup (~236.6 mL): about 339–340 g
- U.S. “legal” cup (240 mL, labeling): about 340–342 g
- Metric cup (250 mL): about 355–360 g
- Imperial cup (284 mL): about 400–405 g
Early Conversion Table For Honey (Place-On-Fridge Helpful)
This table keeps the math simple for common kitchen amounts. It uses the U.S. cup baseline of ~339–340 g and the widely accepted tablespoon figure of ~21 g from the same dataset.
| Measure | Approx. Volume | Honey (g) |
|---|---|---|
| 1 cup (U.S.) | ~236.6 mL | 339–340 g |
| 3/4 cup | ~177 mL | ~254 g |
| 2/3 cup | ~158 mL | ~226 g |
| 1/2 cup | ~118 mL | ~170 g |
| 1/3 cup | ~79 mL | ~113 g |
| 1/4 cup | ~59 mL | ~85 g |
| 2 Tbsp | 30 mL | ~42 g |
| 1 Tbsp | 15 mL | ~21 g |
Why A Cup Of Honey Doesn’t Always Weigh The Same
Honey isn’t uniform like water. Small shifts in moisture and temperature change how tightly it packs in a cup. These are the main movers:
Moisture Content And Floral Source
Wildflower, clover, acacia, buckwheat—each carries a slightly different makeup. Lower moisture means denser honey and a touch more weight per cup. The difference isn’t dramatic, but it can push a cup up or down by several grams.
Temperature During Measuring
Cold honey thickens and traps bubbles when you scoop; warm honey flows and settles more evenly. Cooler jars can under-fill measuring cups, while gently warmed jars settle closer to the true weight.
Crystallization Level
Crystals trap tiny air pockets. If your jar has partially crystallized, you can weigh a little less per measured cup than a fully fluid jar. A brief warm-water bath returns it to a pourable state for more consistent weighing.
How You Fill The Cup
Scraping in thick strands, tapping the cup on the counter, and leveling the top all change the packed amount. With heavy, viscous honey, packing technique matters more than it does for thin liquids.
Use Cases: When Exact Grams Matter Most
Baked Goods And Texture Control
Honey pushes sweetness, browning, and moisture. In breads, swapping 340 g of honey for 340 g of sugar won’t behave the same because honey is mostly sugars plus water. Weigh it so your hydration math stays on target.
Balanced Sweetness In Dressings And Sauces
Small errors swing flavor fast. A “heaping” half cup can quietly add ~20–30 g. That’s enough to tip a vinaigrette or glaze from bright to cloying.
Recipe Scaling For Batches
Going from one loaf to three? Volume errors compound. Weighing 339–340 g per U.S. cup keeps ratios stable when you scale up.
Practical Tips To Measure Honey Cleanly
Prefer A Scale
Place a bowl on the scale, tare to zero, then pour until you hit the target grams. No sticking, no scraping, no guesswork. If a recipe calls for “1 cup,” just use 339–340 g for U.S. cups, or the system-specific value you need.
Warm The Jar Slightly
Set the sealed jar in warm water for a few minutes. It flows easier, traps fewer bubbles, and levels more predictably. Don’t overheat—lukewarm is enough.
Oil Or Wet The Spoon
A drop of neutral oil on the spoon or a quick rinse with hot water helps honey slide off cleanly. You’ll waste less and hit your numbers faster.
Note Your Cup System
If you cook from international sources, lock in which “cup” they use. U.S. customary, U.S. legal (labeling), metric, and imperial cups don’t match. When in doubt, switch to grams.
Close Variant: Grams In One Cup Of Honey With Simple Math
Here’s a clear way to read grams without a calculator. Start with your cup size. Multiply the milliliters of that cup by honey’s typical density (~1.4 g/mL) to get a ballpark weight. Then adjust a few grams for temperature, crystallization, and how tightly you filled the cup.
- U.S. customary cup (236.6 mL) × ~1.4 ≈ ~331 g → use 339–340 g as a practical target.
- U.S. legal cup (240 mL) × ~1.4 ≈ ~336 g → practical target ~340–342 g.
- Metric cup (250 mL) × ~1.4 ≈ ~350 g → common kitchen target ~355–360 g.
- Imperial cup (284 mL) × ~1.4 ≈ ~398 g → kitchen target ~400–405 g.
Because the ingredient is dense and sticky, the small range you see is normal in kitchens. Weighing removes that wobble.
Second Conversion Table: Cup Systems Compared (Honey)
This table sits later for readers who need cross-border clarity. The cup volumes come from labeling and measurement standards; the grams reflect typical kitchen targets for honey’s density. The FDA labeling rule cites 240 mL for a “cup,” which explains why some U.S. nutrition panels round differently (cup = 240 mL).
| Cup System | Exact Volume | Honey Per Cup (g) |
|---|---|---|
| U.S. Customary | 236.6 mL | ~339–340 g |
| U.S. Legal (Labeling) | 240 mL | ~340–342 g |
| Metric | 250 mL | ~355–360 g |
| Imperial (UK) | 284 mL | ~400–405 g |
Worked Examples You Can Copy Straight Into A Recipe
Convert A U.S. Cup To Tablespoons
One tablespoon of honey weighs ~21 g. So a U.S. cup (~339–340 g) equals about 16 tablespoons. If your recipe calls for 8 tablespoons, you’ll add roughly ~168–170 g.
Half Cup For A Small Batch
Using the same baseline, 1/2 cup is ~170 g. This keeps a quick banana bread or granola formula consistent when you scale down.
Metric Cup Recipe
Australian or European recipes often use a metric cup (250 mL). For honey, plan on ~355–360 g per cup. If you swap that into a U.S. recipe without adjusting, sweetness and moisture will creep up.
Common Mistakes With Honey Conversions
Mixing Up Fluid Ounces And Ounces
Fluid ounces measure volume, ounces measure weight. With honey, that mix-up swings grams a lot. Stick to grams for accuracy, or confirm which “oz” the recipe uses.
Scraping A Sticky Cup
Scraping leaves ribbons on the walls of the cup. You might think you added a full cup, but you actually plated less. Pour and weigh directly when you can.
Ignoring Cup System Differences
That old family card might be imperial. A blog post might be metric. A brand’s label might be U.S. legal. Confirm the cup system before you convert.
Quick Reference: Keep These Numbers Handy
- U.S. cup of honey: 339–340 g (how many grams are in 1 cup of honey?—that’s your number).
- 1 tablespoon: ~21 g (fast swaps for dressings and marinades).
- 1/2 cup: ~170 g (easy scaling for small loaf pans).
- Metric cup: ~355–360 g (heavier than U.S. customary).
- Imperial cup: ~400–405 g (heavier again).
When You Should Quote The Exact Keyword In Notes
Writing or sharing a recipe? If your audience will search “how many grams are in 1 cup of honey?” consider adding “1 cup = ~340 g” in the ingredients list. It cuts repeat questions and helps readers who cook by weight.
Bottom Line For Reliable Results
Use a scale and target ~339–340 g per U.S. cup. For other cup systems, match the table above. If the jar is cool or partly crystallized, warm it briefly and re-weigh. That’s it—clean, repeatable, and friendly to any recipe card.
