Temperature isn’t “multiply like length” — scales use offsets (and kelvin starts at absolute zero). If you’ve ever double-checked a fever or a furnace setting, you know small mistakes matter. This tool applies the standard formulas so you don’t have to remember which way the 32 goes.
Celsius originally ran opposite to today’s direction; Fahrenheit anchored to brine and body temperature anecdotes. Kelvin starts where thermal motion hits zero—making it the natural scale for science even when humans still read °C or °F.
°F = °C×(9/5)+32; °C = (°F−32)×(5/9); K = °C + 273.15
Celsius and Fahrenheit are offset linear images of each other, not proportional like kilograms. Kelvin shares Celsius-sized steps but zeroes at absolute zero, so it never uses offsets with Fahrenheit directly—convert through °C.

Short version: To convert Celsius (°C) to Fahrenheit (°F), multiply by 1.8 and add 32. Formula: (C × 9/5) + 32 = F.

Celsius and Fahrenheit are equal at -40 degrees (-40°C = -40°F).
Absolute Zero (0 Kelvin) is the lowest possible temperature where all molecular motion ceases.
Rounding, sensor placement, and model grids differ. Conversion math is deterministic; meteorological storytelling is not.
