FAQ
How does this unit converter work?
It converts your input value into a canonical base unit for the selected category (like meters for length), then converts from the base unit into your target unit.
Does this support metric and imperial conversions?
Yes. Many categories include both metric and imperial units (for example meters ↔ feet, kilograms ↔ pounds, liters ↔ gallons).
Why do I see scientific notation sometimes?
Very large or very small numbers are displayed in scientific notation to keep results readable and avoid long strings of zeros.
Is the converter accurate for temperature?
Yes. Temperature uses correct conversion formulas (Celsius ↔ Fahrenheit ↔ Kelvin) instead of a simple ratio.
