FAQ

How many unit categories are supported?
Seven: Length, Weight, Temperature, Volume, Area, Speed, and Data. Each category includes the most commonly used units.
Does it handle temperature conversions correctly?
Yes. Temperature uses offset-based formulas (not simple ratios), so conversions between Celsius, Fahrenheit, and Kelvin are accurate.
Is the data conversion using binary (1024) or decimal (1000)?
Binary. 1 GB = 1024 MB, 1 MB = 1024 KB, and so on — matching how operating systems and developers typically measure storage.
Can I see a table of common conversions?
Yes. A quick reference table at the bottom automatically shows conversions for 1, 5, 10, 25, 50, and 100 of the selected unit.
