🏋️ Weight Converter

What This Converter Does

This tool converts between all the common units of weight — kilograms, grams, pounds, ounces, stone, and more — in one place. Enter a value in any unit and it gives you the equivalent in the others instantly. Instead of needing a separate converter for each pair of units, this handles the whole family, which makes it the one tool to reach for whenever weight needs translating.

Weight conversion comes up constantly: cooking with recipes from different countries, checking shipping and luggage limits, reading product specs, tracking body weight, or working on any project that mixes metric and imperial measurements. Having every common unit in a single converter saves time and removes the guesswork of remembering individual conversion factors.

The Units and How They Relate

The metric units stack neatly by tens: 1,000 grams make a kilogram, and 1,000 kilograms make a metric tonne. The imperial side is less tidy: 16 ounces make a pound, and 14 pounds make a stone — a unit still widely used for body weight in the UK and Ireland. The bridge between the systems is that one kilogram is about 2.205 pounds, and one ounce is about 28.35 grams.

Because the imperial units do not follow a simple base-ten pattern, converting between them by hand is genuinely fiddly, and mixing systems — say, a recipe that lists some ingredients in grams and others in ounces — is exactly where mistakes happen. A converter that holds all the units at once lets you move between any of them without juggling multiple factors, so you can work confidently across both systems.

Quick Tips

• One kilogram is about 2.205 pounds, and one ounce is about 28.35 grams — the key bridges between systems.
• Sixteen ounces make a pound; fourteen pounds make a stone.
• For baking, convert by weight precisely rather than estimating, since small differences affect the result.
• Round up your own estimate when checking against a shipping or luggage limit to stay safely under.

Frequently Asked Questions

How many grams are in an ounce?

One ounce is about 28.35 grams. So a quarter-pound, which is four ounces, is roughly 113 grams. This converter handles the exact figure for any value.

How many pounds are in a kilogram?

One kilogram is about 2.205 pounds. To go the other way, one pound is about 0.454 kilograms. The converter switches between them instantly.

What is a stone in weight?

A stone is 14 pounds, a unit still commonly used for body weight in the UK and Ireland. So 10 stone is 140 pounds, or about 63.5 kilograms.

Why convert by weight for baking?

Because baking is sensitive to precise quantities — measuring flour by weight rather than volume is far more accurate, and small differences change the result. Converting weights precisely helps your baking turn out as intended.
