Unit Converter

Key features

• Eight categories: Length, Weight, Temperature, Area, Volume, Speed, Data and Time.
• Real formulas for temperature (Celsius ↔ Fahrenheit ↔ Kelvin) rather than rough multipliers.
• A swap button flips From and To in one click, and each category remembers its last unit pair.
• A “1 m = 3.28 ft”-style reference line under the result for quick mental maths.
• Adaptive formatting: everyday results stay readable, while extreme magnitudes switch to scientific notation instead of a wall of digits.
• One-click copy of the full conversion, e.g. “1 m = 3.28084 ft”.

How it works

1. 1

   Pick a category

   The tabs at the top switch between Length, Weight, Temperature, Area, Volume, Speed, Data and Time.

2. 2

   Type the value

   The result updates as you type — there's no button to press.

3. 3

   Choose From and To units

   Pick any two units from the category; the swap button reverses them instantly.

4. 4

   Read or copy the result

   The converted figure is shown large, with the one-unit equivalent and a copy button below it.

Tips for better results

• 💡The Data category uses binary multiples: 1 KB = 1,024 bytes and 1 MB = 1,024 KB, matching how operating systems report file sizes.
• 💡Volume is US customary: the cup is 236.6 ml and the gallon 3.785 L — not the imperial versions.
• 💡For quick back-and-forth conversions, tap the swap button instead of retyping the value in reverse.
• 💡Very small or huge numbers are easier to check in the exponential view, which appears automatically outside the normal decimal range.
