Turnips are a low-calorie, high-water root vegetable often overlooked in protein-focused meal plans — and this turnip protein calculator makes it easy to see exactly how much protein is in any serving you actually eat. Whether you're logging a raw turnip snack, boiled turnip cubes in a stew, or even protein-rich turnip greens, the tool converts your portion into grams with just one click.
Built for people tracking macronutrients, plant-based eaters curious about vegetable protein, and anyone following a calorie-conscious diet, this calculator uses USDA nutrition reference values. You can enter your serving in grams, ounces, cups, or whole turnips, then switch between raw root, cooked root, raw greens, and cooked greens to get a precise, personal result. The breakdown also shows protein density per 100 g and the share of your daily protein target, plus a step-by-step explanation of how the number was calculated.
🥬 Your Turnip Serving
Quick Start Guide
This calculator is built for anyone tracking macronutrients, from plant-based eaters curious about vegetable protein to people following a calorie-conscious diet. Start by picking the turnip form that matches what you are eating — raw root, boiled root, raw greens, or cooked greens. Then enter your serving size in grams, ounces, cups, or whole medium turnips. The preset buttons fill in common portions instantly, and the daily protein target lets you see how much of your day's protein this serving covers.
How the Calculation Works
The calculator uses USDA reference values for protein per 100 grams. After converting your serving to grams, it applies the simple formula:
Protein (g) = serving weight (g) × protein per 100 g ÷ 100
The serving is also converted to a percentage of your daily protein target, and a step-by-step breakdown shows both conversions so you can verify the math yourself.
Worked Examples
Example 1: You eat 200 g of raw turnip root. Raw turnip root has 0.9 g protein per 100 g, so the protein is 200 × 0.9 ÷ 100 = 1.80 g. Against a 50 g daily target, that is 3.6% of your protein for the day.
Example 2: You cook 1 cup of turnip greens. One cup of cooked greens weighs roughly 144 g, and cooked turnip greens have 1.14 g protein per 100 g, giving 144 × 1.14 ÷ 100 = 1.64 g of protein — enough to cover about 3.3% of a 50 g target.
Reference Protein Values
The table below lists the USDA values used in this calculator. Different forms of turnip have different water content, which is why the protein density changes after cooking.
| Turnip form | Protein per 100 g |
|---|---|
| Raw turnip root | 0.9 g |
| Boiled turnip root | 0.7 g |
| Raw turnip greens | 1.5 g |
| Boiled turnip greens | 1.14 g |
Common Mistakes to Avoid
- Confusing raw and cooked servings. Cooking changes both weight and protein density, so pick the form that matches what is actually on your plate.
- Using a cup measurement from memory. Cup weights differ for raw cubed versus boiled turnip, so check the breakdown line that shows the converted gram weight.
- Ignoring the serving weight line and reading only the final protein number. The gram weight is the backbone of the whole calculation.
Frequently Asked Questions
Are turnips a good source of protein? No. Turnips are a low-protein vegetable, and their value comes from volume, fiber, and very few calories. Use this calculator to track the small protein amounts that add up across a whole meal.
Why is the protein per 100 g lower after boiling? Boiling alters water content and can leach some water-soluble nutrients, so the protein density per 100 g shifts slightly. The absolute amount of protein in the same piece of root changes very little.
Do turnip greens count toward protein? Yes. Greens contain noticeably more protein than the root, so including them in your tracking can make a small but real difference over a week of meals.
Can I use this for meal prep? Yes. Weigh the whole batch before cooking, calculate one serving, then multiply by the number of servings you pack. This tool handles the math for a single portion, so you can repeat it per container.
