Common conversions at a glance
Length: 1 mile = 1.609 km · 1 inch = 2.54 cm · 1 foot = 30.48 cm. Weight: 1 kg = 2.205 lb · 1 ounce = 28.35 g · 1 stone = 6.35 kg. Temperature: 0 °C = 32 °F = 273.15 K, and each 1 °C step equals 1.8 °F. The tool computes exact factors — the rounded figures above are just for quick mental estimates.
Frequently asked questions
Why is temperature different from the other units?
Length and weight convert by multiplication, but temperature scales have different zero points, so conversion needs an offset as well as a factor — e.g. °F = °C × 9/5 + 32. The tool handles this automatically.
How precise are the results?
Up to 6 significant digits, using exact standard factors. For everyday use the numbers match official conversion tables.
