What the Weight Converter does

This tool turns one weight unit into another in a single step. Switch between milligrams, grams, kilograms, ounces, pounds and stones without hunting for a formula. It suits anyone weighing parcels, scaling a recipe from metric to imperial, logging gym progress in lbs or stone, or checking homework. There is no app to install and nothing to sign up for.

How to use it

  1. Type the number you want to convert into the Value field.
  2. Open the From dropdown and choose your starting unit (mg, g, kg, oz, lb or st).
  3. Open the To dropdown and pick the unit you want the answer in.
  4. Read the converted result below. It updates as soon as you change a field, and shows up to four decimal places.

Want to go the other way? Just swap the From and To choices. To run a new figure, type over the Value box.

Why convert here

Speed is the main draw: the answer lands instantly, with no page reloads or pop-ups. It is genuinely private too, because every calculation happens on your own device and no weights are uploaded anywhere. The conversion factors are exact (1 kg = 1000 g, 1 lb = 453.59237 g, 1 oz = 28.349523125 g, 1 stone = 6350.29318 g), so the numbers hold up whether you are shipping, baking or tracking weight loss. And it is free, with no account and no usage cap.

Quick tip

Remember the rough anchors and you can sanity-check any result at a glance: 1 kg is about 2.2 lb, 1 stone is 14 lb, and 1 oz is roughly 28 g. These are handy when you only need a ballpark figure.

Treat the output as general reference rather than a certified measurement for trade or medical dosing.
