Frequently Asked Questions
How many kilometres in a mile?
1 mile = 1.60934 kilometres. Conversely, 1 kilometre = 0.62137 miles. A quick approximation: multiply miles by 1.6 to get km, or multiply km by 0.6 to get miles.
How do I convert Celsius to Fahrenheit?
Formula: °F = (°C × 9/5) + 32. For example, 25°C = (25 × 1.8) + 32 = 77°F. To convert Fahrenheit to Celsius: °C = (°F − 32) × 5/9.
How many pounds in a kilogram?
1 kilogram = 2.20462 pounds. To convert kg to lbs, multiply by 2.205. To convert lbs to kg, divide by 2.205. For example, 70 kg = 154.3 lbs.
What is the difference between weight and mass?
Mass is the amount of matter in an object (measured in kg or lbs) and is constant everywhere. Weight is the force of gravity on that mass (measured in Newtons) and varies by location. In everyday use, the terms are used interchangeably, but in science they are distinct.
