Metric vs Imperial: A Quick Conversion Guide
Most of the world uses metric; a few countries use imperial. When recipes, travel or instructions mix the two, a few conversions cover almost everything.
Length
1 inch = 2.54 cm, 1 foot = 30.48 cm, and 1 mile ≈ 1.609 km. A quick mental trick: multiply kilometres by 0.62 to get miles.
Weight
1 kilogram ≈ 2.205 pounds, and 1 pound ≈ 0.454 kg. So to go from kilos to pounds, roughly double and add ten percent.
Temperature
To convert Celsius to Fahrenheit: multiply by 1.8 and add 32. The reverse: subtract 32, then divide by 1.8. The Temperature Converter handles it instantly, along with the Length and Weight converters.
