Lime
Juice

One pound of limes (approximately 454g) is roughly 4–6 Persian limes or 8–12 Key limes. Limes contain about 35% juice by weight — lower than lemons (40–45%) because of their thicker rind-to-flesh ratio. After accounting for peel and seeds, expect approximately 140–170ml from 1 lb of whole limes in a masticating juicer. That's roughly 4.5–6 oz.

Centrifugal juicers extract a bit less efficiently for citrus — plan on 120–155ml from the same pound. If you're scaling a recipe or batch, working by weight is far more reliable than counting fruit, since lime sizes vary significantly between Persian (the large grocery-store variety) and Key limes.

A full 8 oz cup (240ml) of lime juice requires approximately 14–18 Persian limes in a masticating juicer — significantly more than lemons because limes yield less juice per gram of whole fruit. Centrifugal juicers need a few more: roughly 17–22 limes for the same cup.

For Key limes, the math is more extreme — expect 25–35 Key limes per 8 oz cup. They're less juicy by weight and smaller to begin with. Most people use lime juice in smaller quantities (1–2 oz per serving) rather than drinking full cups straight. For a specific quantity and juicer combination, the calculator handles the math in real time.

Five pounds of whole Persian limes (approximately 2,268g) yields roughly 680–850ml in a masticating juicer — about 23–29 oz, or just under a quart. In a centrifugal juicer, expect closer to 590–745ml from the same batch.

At 1–2 oz per serving, 5 lbs of limes gives you 12–28 servings of fresh lime juice. If you're batch-making for cocktails, cooking, or a daily lime-water protocol, one 5 lb bag covers 2–4 weeks easily. The calculator lets you enter any weight and juicer type to get the exact yield.

Three factors account for most variation in lime yield: variety, ripeness, and temperature. Persian limes (the large, seedless kind sold in most grocery stores) yield more juice per gram than Key limes, which have thicker rinds relative to their size. Fully ripe limes — ones that give slightly when squeezed and feel heavy — yield 20–30% more than underripe, firm limes that look equally green.

Temperature is significant for all citrus. Cold-from-the-fridge limes yield about 15% less than room-temperature fruit. Rolling a lime firmly on the counter before cutting breaks down internal juice sacs and can increase yield by 10–15%. Season matters too — winter limes are often drier than summer fruit. The yield ranges on this page assume ripe, room-temperature Persian limes.

Yes — especially for vitamin C. Lime juice contains approximately 30mg of vitamin C per 100ml. Centrifugal juicers introduce oxygen during the high-speed spin, degrading heat-sensitive nutrients. Studies on citrus juicing show 15–25% vitamin C loss in centrifugal extraction versus slow-press methods.

The more practical difference is total yield: a masticating or hydraulic press juicer extracts 15–25% more juice per lime, which means more total nutrients per batch even if concentration is similar. If you're using lime juice primarily for its vitamin C or citric acid content, a masticating juicer gives you more of both per pound of fruit.

No — lime juice has among the lowest sugar content of any fresh juice. At 1.69g of natural sugar per 100ml, lime is even lower-sugar than lemon juice (2.5g/100ml). An entire 8 oz cup of lime juice contains only about 4g of sugar total, with a glycemic impact close to zero.

The sharp tartness comes from citric acid, not sugar — limes register pH 2–2.5, slightly more acidic than lemons. This makes lime juice safe for essentially any blood-sugar protocol and genuinely negligible on a low-carb or ketogenic diet. At only 25 kcal per 100ml, lime juice is often used as a high-impact flavor addition without meaningful caloric or glycemic contribution.

For masticating juicers: peel or at minimum score and halve the lime before feeding it. Unlike lemons — where the peel can act as a feed guide — lime peel contains concentrated essential oils and bitter limonene that overwhelm the juice flavor in a slow juicer. The peel's compounds extract readily under slow pressure and leave the juice harshly bitter and aromatic.

For citrus reamers or hand squeezers: halve and squeeze as-is — the peel stays structurally intact and minimal oil is extracted. For centrifugal juicers: peel first, or use the citrus attachment if your model includes one. The key rule for lime: more so than lemon, keep the peel out of the juice path unless bitterness is intentional.

The primary concern is the same as with lemon: dental enamel erosion. Lime juice has a pH of approximately 2–2.5, acidic enough to soften enamel with direct, repeated exposure. Use a straw for straight lime juice, rinse with water immediately after, and wait 30–60 minutes before brushing.

People with acid reflux or GERD should be cautious — lime juice is more acidic than lemon and can aggravate symptoms. For most healthy adults, 1–4 oz daily is well-tolerated. High-volume lime juice (8+ oz daily, undiluted) is uncommon because the tartness is intense; most protocols that use lime dilute it significantly. Despite the acidity, lime juice does not acidify blood pH — the body regulates blood pH tightly regardless of dietary acid intake.

Lime's sharper, more floral tartness (compared to lemon) makes it a particularly effective flavor bridge for tropical and high-sugar produce. Classic juicing pairings: watermelon (lime cuts the flat sweetness dramatically), pineapple (lime lifts and brightens the tropical profile), cucumber (lime adds edge to an otherwise mild juice), and ginger (shared intensity, excellent for immunity and anti-inflammatory blends).

In green juices, lime works better than lemon for spinach and lighter greens — the floral note is less dominant than lemon's sharpness. Add 0.5–1 oz per 16 oz serving as a finishing note. For citrus blends, lime combined with grapefruit and a small amount of honey is a well-balanced combination. The calculator supports multi-ingredient batches with combined nutrition.

Yes — and this is among the best-supported health claims for citrus juice. Citric acid in lime juice increases urinary citrate levels, which inhibits calcium crystallization — the mechanism behind calcium oxalate kidney stones, the most common type. The citric acid content in lime juice is high (approximately 47g/L), comparable to lemon juice, making it effective for this purpose.

Research supports roughly 4 oz (120ml) of fresh citrus juice daily as a meaningful preventive dose for people prone to calcium oxalate stones. Lime can substitute for lemon in kidney stone prevention protocols — citric acid is the active compound, and both fruits contain it in similar concentrations. This is a preventive strategy, not a treatment. Consult a urologist if you have a history of kidney stones before starting any citrus-based protocol.

Fresh-squeezed lime juice keeps best for 2–3 days in a sealed, airtight container in the refrigerator. Vitamin C degrades substantially after that, and the flavor flattens. Minimize air exposure — fill the container completely and avoid leaving headspace.

Masticating-pressed lime juice holds slightly longer than centrifugal juice due to lower initial oxidation. For batch-making, freezing immediately after juicing works well — lime juice freezes cleanly and retains most of its vitamin C and citric acid for 3–4 months. One standard ice cube tray slot holds approximately 30ml (1 oz), which makes portioning easy for daily lemon-water, cocktail use, or cooking.
