Frequently Asked Questions
KB is decimal (1000 bytes) as defined by SI. KiB is binary (1024 bytes) as defined by IEC. Traditionally 'KB' was used ambiguously for both, but for precision, use KiB when meaning 1024. Our converter supports both.
°C = (°F - 32) × 5/9. Reverse: °F = °C × 9/5 + 32. Kelvin: K = °C + 273.15. Our converter applies these formulas automatically for the three main temperature scales.
Yes. We include nautical mile (1852 m), knot (nautical mph), fluid ounce (US and UK), imperial gallon vs US, and other units common in specific domains (marine, aviation).
