Potato Calories by Weight
Raw potato is 77 cal per 100g regardless of variety. Sweet potato is 86 cal per 100g.
| Preparation | Per 100g | Notes |
|---|---|---|
| Raw potato | 77 cal | All varieties similar |
| Baked, plain | 93 cal | After moisture loss |
| Boiled | 87 cal | Slight water absorption |
| Mashed (with butter, milk) | 113 cal | Per 100g cooked |
| French fries | 312 cal | Heavy oil absorption |
| Loaded baked (with toppings) | ~280 cal | Butter, cheese, bacon, sour cream |
How Cooking Changes Weight
Boiling adds 10-15% (water absorption). Baking loses 15-25% (moisture out). Frying loses 40-50% of the original water but replaces some with absorbed oil. Always pair raw nutrition data with raw weights or cooked with cooked.
Estimating Without a Scale
Computer mouse = small (130g). Closed fist = medium (170g). Bigger than fist = large (250g). Baseball = extra-large (300g+). Five fingerlings = roughly one medium potato.
