Temperature Converter
Convert
Temperature uses an affine (not linear) relationship between °C, °F and K — the engine handles the offsets correctly.
Temperature is a measure of thermal energy. The three common scales — Celsius (°C), Fahrenheit (°F) and Kelvin (K) — differ by both a scale factor and an offset, so they can't be converted with a simple multiply. This converter applies the correct affine transformations (°F = °C×9/5 + 32; K = °C + 273.15).
Temperature conversion matters in electronics (datasheet ratings are often in °C; some tools use °F), in cooking, and in science (Kelvin is the SI base, with 0 K = absolute zero). Watch for the offset: 0 °C is 32 °F, not 0 °F.
Frequently asked questions
°F = °C × 9/5 + 32. For example, 25 °C = 77 °F.
0 K = −273.15 °C = −459.67 °F. It's the lowest possible temperature, where thermal motion ceases.
Because the scales have different zero points (offsets). A linear multiply would give wrong answers — the converter applies the correct affine formula.
