Common conversion factors

Temperature is unlike other units: multiplying by a factor is not enough, because the scales have different zero points.

°F = (°C × 9/5) + 32
°C = (°F − 32) × 5/9
K = °C + 273.15

Example: 25°C = (25 × 1.8) + 32 = 77°F.

How many centimetres are in an inch?

One inch is exactly 2.54 centimetres. This is an official definition, not an approximation.

How do I convert Celsius to Fahrenheit?

Multiply the Celsius value by 9/5 (that is 1.8) and add 32. So 25°C equals 77°F.

How many kilograms are in a pound?

One pound equals 0.45359237 kilograms, roughly 0.454 kg.
