Frequently Asked Questions
What is a conversion factor?
It is the multiplier that changes one unit into another unit of the same quantity.
Why is temperature different?
Temperature scales have different zero points, so conversion requires adding or subtracting offsets.
Can I convert any two units?
Only units measuring the same type of quantity can be converted directly.
Why do some results have many decimals?
Some unit relationships do not produce short decimal values, so rounding is used for display.
Is this precise enough for technical work?
It is useful for everyday conversions. High-stakes technical work should verify precision, rounding, and standards.
