Select the "Length" category, enter your value in kilometres, and the miles equivalent appears instantly alongside all other length units. 1 km = 0.621371 miles. For a quick mental estimate, multiply km by 0.6.

Select the "Temperature" category and enter degrees Celsius. The Fahrenheit conversion appears automatically using the formula °F = (°C × 9/5) + 32. For example, 20°C = 68°F, 100°C = 212°F (boiling point of water).

Select "Weight / Mass" and enter kilograms. 1 kg = 2.20462 lbs. So 70 kg = 154.3 lbs. The converter also shows stones and ounces simultaneously.

Mass is the amount of matter in an object (measured in kg or lbs) and stays the same everywhere. Weight is the force of gravity acting on that mass (measured in Newtons) and varies slightly by location. In everyday use, "weight" and "mass" are used interchangeably and both use kg/lbs.

Yes — use the "Volume" category for fluid conversions (litres, millilitres, cups, fluid ounces, tablespoons, teaspoons). Note that US cups and metric measurements differ — 1 US cup = 236.6 ml. For converting weight-based cooking measurements, use the "Weight" category.
