Understand the concept

In everyday usage, “weight” is used as a synonym for mass. In science, mass is measured in kg and weight is a force (depends on gravity). In everyday conversions, what you usually want is to convert mass.

The metric system uses grams (g) and kilograms (kg). The imperial system uses pounds (lb) and ounces (oz), and in the United Kingdom stone (st) also appears.

Practical example: 1 kg ≈ 2.2046 lb. Therefore, 10 kg ≈ 22.05 lb. And 1 lb = 16 oz.

Common mistakes include confusing oz (mass) with fl oz (volume) and using aggressive rounding in submissions, recipes or dosages.

Use this converter to standardize units in international purchasing, cooking and logistics.

How to use this tool

  1. Select the source unit (e.g. kg).
  2. Select the target unit (e.g. lb).
  3. Enter the value and read the result.
  4. If shipping, consider rounding up according to the carrier's rules.

FAQ

What is the difference between lb and oz?

1 lb = 16 oz.

Stone is used where?

It is common in the UK for body weight (1 st = 14 lb).

Is Oz the same thing as fl oz?

No. oz is mass; fl oz is volume.

Why doesn't 1 kg turn into 2.2 lb exactly?

Because the conversion uses a standardized factor with several places.

What is a common mistake?

Mixing mass and volume or rounding too early.
