From Fahrenheit
Fahrenheit to Celsius
C = (F − 32) × 5/9
Convert °F to °C — translate U.S. weather, recipes, body temperature to metric.
°F → °C →Fahrenheit to Kelvin
K = (F − 32) × 5/9 + 273.15
Convert °F to K — bridge U.S. units to absolute scale used in physics.
°F → K →Fahrenheit to Rankine
R = F + 459.67
Convert °F to °R — simplest absolute scale conversion, just add 459.67.
°F → °R →Three focused converters for translating Fahrenheit to each of the other three standard temperature scales. Each is a one-direction converter with the formula visible, the substituted arithmetic shown step-by-step, and a static reference table for the temperatures most readers actually look up.
Fahrenheit is the dominant scale in U.S. consumer use (weather, oven, body temperature). These converters bridge to the metric world (Celsius), the physics world (Kelvin), and some U.S. engineering contexts (Rankine).
When to use these converters
Fahrenheit to Celsius is the inverse of the world's most-searched temperature conversion — used for translating U.S. weather forecasts, recipes, and body temperatures to the metric scale used in most other countries. Fahrenheit to Kelvin is less common but shows up in U.S. physics homework. Fahrenheit to Rankine is the simplest of the three (same-sized degree, different zero — just add 459.67).
Frequently Asked Questions
- What's the formula for Fahrenheit to Celsius?
- C = (F − 32) × 5/9. Subtract 32 to align the zero points, then scale down by 5/9 to Celsius-sized degrees.
- What's the formula for Fahrenheit to Kelvin?
- K = (F − 32) × 5/9 + 273.15. Convert to Celsius first (subtract 32, scale by 5/9), then shift the zero to absolute zero by adding 273.15.
- What's the formula for Fahrenheit to Rankine?
- R = F + 459.67. The Rankine and Fahrenheit scales share the same-sized degree; Rankine's zero is at absolute zero (459.67°F below Fahrenheit's zero).
