Lemon juice, Cups to Grams & Grams to Cups
1 cup of lemon juice = 240 grams · 100g = 0.42 cups
Lemon juice weighs about 240 grams per cup, near water, and brings acidity and brightness to both sweet and savoury cooking. As a rough guide, one medium lemon yields about 3 tablespoons of juice, so a cup takes five or six lemons. Bottled juice works but lacks the aroma of fresh.

How to measure lemon juice accurately
For the most reliable baking results, weigh lemon juice on a kitchen scale rather than scooping by volume. One US cup of lemon juice weighs about 240 grams (8.47 oz), but the exact figure changes with how tightly it's packed and the brand. Scooping straight from the bag compacts lemon juice and can leave you 15 to 20% over, so spoon it into the cup and level it off for the closest match to the figures above. Use the tables for quick reference, or the converter for any custom amount in cups, grams, ounces or tablespoons.
Tip: Roll a lemon firmly on the counter and warm it briefly before juicing to release more liquid from the same fruit.
