Temperature scales differ twice over: where zero sits and how wide degrees stretch. Fahrenheit divides the freeze–boil span into 180 degrees against Celsius's 100 — hence multiply-by-1.8 — while the −32 correction reconciles their differing zero points.
Kelvin shifts Celsius down by absolute zero, the coldest possible temperature. Because it starts at true zero, scientific formulas use Kelvin exclusively; no negative Kelvin exists.

Temperature Converter: Switch between Celsius, Fahrenheit and Kelvin with offset-aware math. Formula: °F = °C × 9⁄5 + 32. Example: A warm 77 °F day converts to (77 − 32) ÷ 1.

A warm 77 °F day converts to (77 − 32) ÷ 1.8 = 25 °C, or 298.15 K — beach weather on every scale.
