Unit Converter
Convert between common metric and imperial units used in Australia.
Result
62.137 mi
How it's calculated
- Most conversions multiply by a fixed factor: 1 km = 0.621371 miles, 1 kg = 2.20462 pounds, 1 litre = 0.264172 US gallons, and 1 inch = 2.54 cm.
- Converting the other way (miles to km, pounds to kg, cm to inches) divides by the same factor.
- Celsius to Fahrenheit multiplies by 9/5 (1.8) and then adds 32.
- Results are shown to three decimal places, with trailing zeros removed.
Worked examples
100 kilometres to miles
100 × 0.621371 = 62.1371, which the calculator shows as 62.137 miles.
25 °C to °F
25 × 9/5 = 45, and 45 + 32 = 77. So 25 °C is 77 °F.
180 centimetres to inches
180 ÷ 2.54 = 70.866 inches (about 5 feet 11 inches).
10 kilograms to pounds
10 × 2.20462 = 22.0462, which the calculator shows as 22.046 pounds.
Assumptions and notes

Frequently asked questions
Does it use US or imperial gallons?
US gallons. A US gallon is about 3.785 litres, while an imperial (UK) gallon is about 4.546 litres, so results will differ if you are comparing with imperial gallons.
How do I convert Fahrenheit back to Celsius?
This calculator converts Celsius to Fahrenheit only. To go back, subtract 32 and multiply by 5/9. For example, 77 °F − 32 = 45, and 45 × 5/9 = 25 °C.
How many kilometres is 60 miles?
Choose miles to kilometres. 60 ÷ 0.621371 = 96.56, so 60 miles is about 96.56 km.
How accurate are the results?
The conversion factors are rounded to about six significant figures and answers are shown to three decimal places, which is accurate enough for everyday use.
