Frequently Asked Questions

How accurate are the conversions?
The calculator uses exact conversion factors defined by international standards (e.g., 1 inch = 2.54 cm exactly). Results are displayed to several decimal places for precision.
Why is temperature conversion different from other units?
Temperature scales have offsets (e.g., 0°C = 32°F), so conversion requires both multiplication and addition, unlike length or weight which use simple ratios.
