Frequently Asked Questions
How accurate are the conversions?
All conversions use precise conversion factors (e.g., 1 inch = 25.4 mm exactly). Results are displayed to up to 10 significant figures and rounded to remove floating-point noise.
Why does temperature conversion work differently?
Unlike most units, temperature conversions are not simple multiplications — they require offset formulas. For example, °C to °F is (°C × 9/5) + 32, not just a ratio.
Can I convert in the reverse direction?
Yes — just swap the From and To dropdowns. You can also click the swap button between them to reverse the conversion instantly.
