Peas are one of the lowest-fat foods in the legume family, but knowing the exact number is still useful. The Pea Fat Calculator tells you exactly how much fat is in your portion of cooked, raw, frozen, canned, or split peas — measured in grams, calories from fat, and as a share of your daily fat budget.
This tool is built for anyone who tracks macros, follows a low-fat meal plan, or simply wants to build balanced plates without guessing. Just choose the pea type, enter your serving size in grams, ounces, or cups, and set an optional daily fat target. The calculator does the conversion and gives you a quick nutrient snapshot, plus a step-by-step breakdown so you can see how the number was calculated.
Because plain peas contain almost no fat, the results also highlight an important practical point: the fat in a pea dish usually comes from the butter, oil, or creamy sauce added during cooking, not from the peas themselves. This calculator keeps portion realities clear for meal planning and macro tracking.
🥬 Pea Fat Calculator
Work out the fat content of your pea portion — choose the pea type, enter an amount, and see grams of fat, calories from fat, and how it fits your daily target.
How to Use This Tool
Start by picking the pea product that matches your meal: cooked green peas, raw green peas, frozen cooked peas, canned peas, or cooked split peas. Each type has its own fat value and cup weight, so choose the closest match. Enter the amount you plan to eat and select grams, ounces, or cups. Grams give the most accurate result. If you use cups, the tool applies a typical gram weight for that pea form, such as 160 g per cup for cooked green peas.
The daily fat target field is optional. The default 70 g suits a typical 2000-calorie eating pattern, but you can replace it with your own macro goal. After clicking Calculate, you will see total fat, calories from fat, the percentage of your daily target, and the FDA Daily Value percentage based on 78 g of fat per day. A step-by-step breakdown shows each conversion.
Pea Fat Reference Table
Values are for plain peas without added oils or sauces. Cooking method changes fat only when fat is added.
| Pea Form | Fat per 100 g | Approx. Cup Weight | Notes |
|---|---|---|---|
| Green peas, cooked | 0.40 g | 160 g | The standard boiled or steamed side dish. |
| Green peas, raw | 0.40 g | 145 g | Ideal for salads or light cooking. |
| Frozen peas, cooked | 0.40 g | 160 g | Nutrient profile similar to fresh cooked. |
| Canned peas, drained | 0.30 g | 180 g | Fat slightly lower; check sodium. |
| Split peas, cooked | 0.40 g | 200 g | Common in soups and dal. |
Values are rounded from standard nutrition reference data. Package labels may differ slightly.
The Math Behind the Calculation
The calculator converts your portion to grams first. One ounce equals 28.3495 g, and one cup uses the approximate cup weight for the selected pea type. Then it applies the formula:
Fat (g) = portion weight (g) × fat per 100 g ÷ 100
Calories from fat are fat grams multiplied by 9, and the percentage is fat divided by your target, times 100.
Example: 1 cup of cooked green peas weighs about 160 g. Fat = 160 × 0.40 ÷ 100 = 0.64 g. Calories from fat = 0.64 × 9 = 5.76 kcal. Against a 70 g daily target, that is about 0.91% of your fat budget.
Why Peas Are a Low-Fat Win
Peas are legumes, and legumes store energy mainly as protein and complex carbs rather than oil. A 100 g serving of cooked green peas has only about 0.4 g of fat, while the same weight of many nuts, seeds, or avocados delivers 15 g to over 50 g. The little fat peas do contain is mostly unsaturated, and they come with fiber, plant protein, vitamin K, folate, and B vitamins.
The fat in a pea dish almost always comes from added butter, oil, cheese, or cream. One tablespoon of butter has about 11.5 g of fat — roughly what you would find in nearly thirty 100 g portions of plain cooked peas. Peas are equally useful for protein tracking, so pair this tool with the pea protein per 100g calculator to compare protein and fat side by side.
Limitations & Accuracy Notes
Nutrition values are averages; variety, maturity, processing, and measuring method all cause small differences. Cup weights are approximate because peas pack differently depending on whether they are drained, mashed, or measured with cooking liquid. Canned peas can vary with added seasoning and liquid content. This calculator estimates fat only and is not a substitute for professional medical nutrition advice. For very low-fat therapeutic diets, check with a registered dietitian. For everyday tracking, a food scale and package labels give the best precision.
Frequently Asked Questions
Are peas high in fat? No. Plain green peas are one of the leanest legume options, with well under 0.5 g of fat per 100 g. Even a full cup stays below 1 g of fat.
Does cooking add fat to peas? Only if you add something fatty. Boiling, steaming, or microwaving plain peas keeps their fat content unchanged, but a tablespoon of oil or butter in the pot adds 11–14 g of fat to the dish.
Are split peas the same as green peas? Split peas are dried field peas, usually cooked into soups or dal. Their cooked fat content is similar, about 0.4 g per 100 g, but their calorie density is a bit higher, so measure portions by cooked weight.
