Weight Conversion Tips

The metric system uses kilograms and grams, while the US and UK use pounds and ounces. One kilogram equals approximately 2.205 pounds. In the UK, body weight is often expressed in stone (1 stone = 14 pounds = 6.35 kg). For precious gems, the carat (0.2 grams) is the standard unit. Tonnes (metric tons) and US tons differ slightly: 1 metric tonne = 1000 kg, while 1 US ton = 907.185 kg.

When to Use a Weight Converter

Use this converter when traveling between metric and imperial countries, tracking fitness goals across apps that use different units, shipping packages internationally (carriers may use different weight systems), cooking with recipes from different countries, or working with specialized units like carats for gemstones or grains for ammunition.

Expert Tips

• ✻For body weight, remember that 1 stone = 14 pounds - this unit is standard in the UK but rarely used elsewhere
• ✻The troy ounce (31.1g) used for precious metals differs from the standard avoirdupois ounce (28.35g) - always verify which system applies
• ✻When converting cooking measurements, note that dry ingredients measured by volume can vary significantly - weighing in grams is always more accurate
