Results update as you type, and every field accepts the units shown in its menu.
How it works
Each input is converted independently, so fill in only what you need.
Inputs explained
| Field | What to enter |
|---|---|
| Centimetres | A number |
| Metres | A number |
| Kilometres | A number |
| Kilograms | A number |
| Grams | A number |
| Litres | A number |
| Celsius | A number |
What each result means
- Centimetres in inches = [Centimetres] ÷ 2.54
- Metres in feet = [Metres] ÷ 0.3048
- Kilometres in miles = [Kilometres] ÷ 1.609344
- Kilograms in pounds = [Kilograms] ÷ 0.45359237
- Grams in ounces = [Grams] ÷ 28.349523125
- Litres in US gallons = [Litres] ÷ 3.785411784
- Celsius in Fahrenheit = [Celsius] × 9 ÷ 5 + 32

Formula
in = cm ÷ 2.54; ft = m ÷ 0.3048; mi = km ÷ 1.609344lb = kg ÷ 0.45359237; oz = g ÷ 28.3495; US gal = L ÷ 3.78541; °F = °C × 9/5 + 32Worked example
Inputs — Centimetres: 30; Metres: 1.8; Kilometres: 10; Kilograms: 70; Grams: 100; Litres: 1; Celsius: 25.
Results — Centimetres in inches = 11.811 in; Metres in feet = 5.906 ft; Kilometres in miles = 6.214 mi; Kilograms in pounds = 154.324 lb; Grams in ounces = 3.527 oz; Litres in US gallons = 0.2642 US gal; Celsius in Fahrenheit = 77 °F.
