Metric Tonne vs US Ton

A metric tonne and a US short ton are different units.

• 1 metric tonne = 1,000 kg;
• 1 US short ton = 907.18474 kg.

A metric tonne is therefore heavier than a US short ton.

Metric Tonne vs Imperial Long Ton

An imperial long ton is also different from a metric tonne.

• 1 metric tonne = 1,000 kg;
• 1 imperial long ton ≈ 1,016.0469 kg.

The long ton is slightly heavier than a metric tonne.

Weight vs Mass

In everyday language, the terms weight and mass are often used interchangeably. Technically, however, they are different concepts.

Mass describes the amount of matter in an object and is commonly measured in kilograms.

Weight is a force caused by gravity and can technically be measured in newtons.

This converter follows everyday convention and converts common mass units such as kilograms, pounds and ounces.

Weight Converter in Australia

Australia uses the metric system for most official and everyday measurements. Kilograms and grams are therefore the most common units for body weight, food, parcels and general mass measurements.

Pounds, ounces and stones may still appear in:

• International websites;
• US and UK product specifications;
• fitness information;
• cooking recipes;
• shipping information; and
• historical measurements.

Weight Converter for Body Weight

Body weight is commonly recorded in kilograms in Australia but may be displayed in pounds or stones internationally.

For example:

For weight-related health calculations, you can also use the BMI Calculator or Ideal Weight Calculator.

Weight Converter for Cooking

Cooking recipes may use grams, kilograms, ounces or pounds.

Common conversions include:

• 1 oz ≈ 28.35 g;
• 4 oz ≈ 113.4 g;
• 8 oz ≈ 226.8 g;
• 16 oz = 1 lb ≈ 453.6 g; and
• 1 kg ≈ 2.2046 lb.

Note that weight conversion is different from volume conversion. A gram cannot always be converted directly to millilitres without knowing the density of the ingredient.

Weight Converter for Shipping

Shipping providers may use kilograms or pounds depending on the country and carrier.

For example:

Always check whether the carrier uses actual weight, volumetric weight or chargeable weight when estimating freight costs.
