How weight units are converted

A weight converter changes values between grams, kilograms, milligrams, pounds, ounces, and related units. It is useful for recipes, body weight, shipping, product specifications, logistics fees, and international shopping.

Different fields use different units. Food and medicine often use grams or milligrams, body weight may use kilograms or pounds, and overseas products may use ounces or pounds.

Formula or logic

  • 1 kilogram = 1,000 grams
  • 1 pound = 0.453592 kilograms
  • 1 ounce = 28.3495 grams

Example

If a recipe lists 8 oz, that is about 226.8 grams. If a package weighs 5 lb, it is about 2.27 kilograms.

Common questions

Are weight and mass the same?

In daily unit conversion they are often used together, but in physics they are different. For recipes, shipping, and shopping, common unit conversion is usually sufficient.

How are pounds and ounces related?

1 pound equals 16 ounces. Both are common in overseas products and recipes.

Can this be used for shipping fees?

It can help convert weight, but actual shipping fees may also depend on dimensional weight, destination, carrier, and service rules.
