Frequently asked questions

How do I convert cm to inches?

Divide centimetres by 2.54 to get inches. For example, 30 cm ÷ 2.54 = 11.81 inches. To go the other way, multiply inches by 2.54. The exact relationship is 1 inch = 2.54 centimetres — this is a defined, exact conversion, not an approximation. For quick mental arithmetic, dividing by 2.5 gives a result within 2% of the exact value.

How do I convert kg to lbs?

Multiply kilograms by 2.20462 to get pounds. A useful shortcut: double the kg figure and add 10% — this gives a result accurate to within 0.5%. For example, 70 kg: double = 140, add 10% = 154 lbs (exact: 154.3 lbs). To convert lbs to kg, divide by 2.20462 (or halve and subtract 10% for a quick estimate).

How do I convert Celsius to Fahrenheit?

The formula is °F = (°C × 9/5) + 32, or equivalently, °F = (°C × 1.8) + 32. For example, 25°C: 25 × 1.8 = 45, plus 32 = 77°F. A mental shortcut for everyday temperatures: double the °C, subtract 10%, then add 32. For 20°C: double = 40, minus 10% = 36, plus 32 = 68°F (exact: 68°F). To convert the other way: subtract 32 and divide by 1.8.

What is 100 cm in feet and inches?

100 cm = 39.37 inches = 3 feet 3.4 inches (usually written 3′3″). To convert: 100 ÷ 2.54 = 39.37 total inches. 39 ÷ 12 = 3 feet remainder 3 inches. The calculation works for any cm value: divide by 2.54 for total inches, then divide by 12 to separate feet and remaining inches.
