How this works

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

Fixed points: −40° is equal in both scales; 0 °C = 32 °F; 37 °C = 98.6 °F; 100 °C = 212 °F.
US gallon 3.785 L vs UK imperial gallon 4.546 L — about 20% larger.
US ton 2,000 lb · imperial ton 2,240 lb · metric tonne 1,000 kg.

How many pounds is 1 kilogram?

2.20462 lb. For mental arithmetic, double the kilograms and add 10% — 70 kg gives 140 + 14 = 154 lb, exact to the pound.

How do I convert Celsius to Fahrenheit?

Multiply by 9/5 and add 32. So 25 °C = 25 × 1.8 + 32 = 77 °F.
