Frequently Asked Questions
How many pounds are in a kilogram?
There are approximately 2.20462 pounds in one kilogram. As a quick mental estimate, multiply kg by 2.2 to get pounds. For example, 50 kg ≈ 110 lbs, 80 kg ≈ 176 lbs.
What is a stone in weight?
A stone is a unit of weight used in the UK and Ireland equal to 14 pounds or 6.35 kilograms. Body weight in the UK is commonly expressed in stones and pounds — for example "11 stone 5 pounds" means (11 × 14) + 5 = 159 lbs = 72.1 kg.
What is the difference between weight and mass?
Strictly speaking, mass (measured in kg or g) is the amount of matter in an object, while weight is the force of gravity on that mass (measured in Newtons). In everyday life the terms are used interchangeably because we experience constant gravity on Earth. The units in this converter are technically mass units but are universally called "weight" in common usage.
How do I convert grams to cups for cooking?
Grams to cups depends on the ingredient's density — it's not a fixed conversion. Water is 240g per cup, flour is about 120g per cup, and sugar is about 200g per cup. This converter handles gram-to-gram weight conversions only. For cooking volume conversions, use a dedicated cooking measurement converter.
