Are the conversion factors mathematically exact?

Yes. All conversion factors are based on internationally ratified ISO and NIST standards (e.g. exactly 1 inch = 2.54 centimeters, 1 avoirdupois pound = 0.45359237 kilograms).

Linear Distance: 1 inch $\equiv 0.0254$ meters, 1 mile $\equiv 1609.344$ meters, 1 nautical mile $\equiv 1852$ meters.
Mass: 1 pound $\equiv 0.45359237$ kilograms, 1 ounce $\equiv 28.349523125$ grams.
Affine Temperature: $T_C = (T_F - 32) \times 5/9 = T_K - 273.15$.

Why Temperature Calculations Require Special Treatment

Most unit conversions represent direct linear ratios through an origin of zero: ten centimeters is exactly double five centimeters. Temperature scales possess arbitrary zero points (e.g. 0°C is 32°F, while 0 K is absolute zero). This converter routes all thermodynamic queries through standardized Celsius pivot functions, preventing proportional skew.
