Lemon Juice ingredient guide →1 ounce of Lemon Juice in cups
1 ounce of lemon juice = 0.12 US cups. That's based on a 244 g per cup baseline. Because lemon juice can shift with pour speed and temperature, weighing is usually more accurate than measuring by volume.
Answer
0.12 cups
Based on lemon juice density of 1.03 g/ml

What the sources say lemon juice weighs
Published values, quoted at the exact measure each source lists. Sources round differently and assume different fill techniques — which is why they rarely agree to the gram.
| Source | Listed measure | Weight |
|---|---|---|
| USDA FoodData Central | 1 fl oz | 30.5 g |
| USDA FoodData Central | 1 cup | 244 g |
| King Arthur Baking | 1 tbsp | 14 g |
CupOrGram standardizes on 244 g per cup (15 g per tablespoon, 5 g per teaspoon) and uses that single value on every page — how we reconcile the sources.
Why this conversion varies
Lemon Juice usually pours more consistently than dry ingredients, but measurements can still shift.
- Viscosity affects how quickly a measuring cup empties.
- Temperature can slightly change density and flow behavior.
- This page uses a consistent 244 g per cup baseline for repeatable conversions.
Why this conversion matters
Lemon Juice controls batter flow and moisture balance. Reliable conversion helps avoid thin batters, dense crumbs, or under-hydrated doughs.
Practical baking use
Freshly squeezed or bottled citrus juice. Acidic (pH 2-3) and bright-flavoured. Use this conversion when balancing batter hydration, glazes, and syrups.
- Measure at a consistent temperature for better repeatability.
- For viscous liquids, scrape cups and spoons fully to reduce residue loss.
FAQ
How much is 1 ounce of lemon juice in US cups?
1 ounce of lemon juice is 0.12 US cups using a 244 g per cup baseline.
Is 8 oz of lemon juice the same as 1 cup?
0.93 cups — 8 oz by weight of lemon juice is not 1 US cup. A cup of lemon juice weighs 244 g (8.6 oz). Ounces on this page are weight, not fluid ounces — the "8 oz = 1 cup" rule only holds for water-like liquids.
Is it better to weigh lemon juice for baking?
Usually yes. Weight-based measuring reduces shifts from pour speed and temperature, so your results are more repeatable.

Recipe Context for Lemon Juice
For syrups: viscosity can trap residual liquid in measuring tools.
For batters: precise liquid amount controls final thickness and rise.
For glazes: even small liquid changes alter flow and set time.
Common Pitfalls
- Switching brands without re-checking weight can change texture and bake time.
- Using volume-only measurements for dense ingredients can overshoot recipe targets.
- Viscous liquids leave residue in cups and spoons, reducing accuracy.
Brand Variance Example
Baseline on this page: 1 cup lemon juice = 244g. Real-world range can shift by about 4% because liquids are usually more stable than dry ingredients, but viscosity and temperature still matter.
Example for 2 cups: baseline 488g, common range 468g-508g. If your bake is texture-sensitive, start with the lower bound and adjust after a test batch.
