Unit converter
Convert common global units for length, weight, and temperature.
How to use this tool
Convert between eight length, weight, and temperature units in your browser.
Convert a length, weight, or temperature value to another compatible unit for travel, shopping, and everyday comparisons. Supported units are km, mi, m, ft, kg, lb, °C, and °F.
💡 3 Quick Steps to Get Started
Enter the number to convert, such as 32.
Choose compatible source and target units directly, such as °F to °C.
The result updates as you edit. 32 °F gives 0 °C; incompatible unit pairs display a warning.
When it helps
Supports km, mi, m, ft, kg, lb, °C, and °F, with conversions allowed only within the same unit group.
How it works
Length and weight use exact conversion constants through a base unit, while temperature uses linear formulas. Display formatting can round the shown value for the selected locale.
Worked example
Converting 1 km to mi gives about 0.621371 mi, and 32°F equals 0°C.
Limits and data handling
Length, weight, and temperature cannot be converted across groups; an incompatible pair shows no numeric result. The page formats the result for the current locale, so the displayed digits can be rounded.
Conversion runs only in the current browser. The entered value and result are not sent to the GoGo Tools backend or stored by the site.

This browser calculator offers eight units only: km, mi, m, ft, kg, lb, °C and °F. Select units of the same group; for example32 °F→0 °C. Length and weight use fixed factors; temperature uses°F=°C×9/5+32. Results use floating-point arithmetic and display rounding, without certified measurement precision.

FAQ
Unit converter: Which units can I select?
Length supports km, mi, m, and ft; weight supports kg and lb; temperature supports °C and °F. The input must be a finite number the browser can represent.
Unit converter: How is the result calculated?
Length converts through meters and weight through kilograms, using 1 mi = 1609.344 m, 1 ft = 0.3048 m, and 1 lb = 0.45359237 kg. °F and °C use linear formulas.
Unit converter: What compatibility and display limits apply?
Length, weight, and temperature cannot be converted across groups; an incompatible pair shows no numeric result. The page formats the result for the current locale, so the displayed digits can be rounded.
Unit converter: Are my input and result uploaded?
