FAQ

What unit categories are supported?

Length, weight, and temperature — covering the most commonly needed conversions.

Why does the result show so many decimal places sometimes?

Some conversions (like ounces to metric tons) don't land on a clean number — the result shows up to 6 decimal places for length/weight and 4 for temperature, so nothing gets silently rounded away.

Is this accurate for scientific or engineering use?

Conversions use standard, precise conversion factors, suitable for everyday and professional use alike.
