Frequently asked questions
Why is temperature calculated differently from the rest?
Length, weight and speed are proportional conversions (multiply by a factor), while Celsius, Fahrenheit and Kelvin use formulas with an offset, not just a scale factor.
How many decimal places does the result show?
It's rounded to 4 decimal places to keep precision without being impractical to read.
