Celsius ↔ Fahrenheit
🌡️°F = (°C × 9/5) + 32
°C = (°F - 32) × 5/9
Celsius ↔ Kelvin
🔬K = °C + 273.15
°C = K - 273.15
Advanced Conversions
Fahrenheit to Kelvin
K = (°F - 32) × 5/9 + 273.15
1. First subtract 32 from °F
2. Multiply the result by 5/9
3. Add 273.15 to get Kelvin

Quick Reference Guide
Quick Tips
- • Double °C, add 30 (≈ °F)
- • Subtract 30, halve (°F ≈ °C)
- • Add 273.15 (°C to K)
- • 1°C = 1.8°F change
Remember
- • Absolute zero: 0K
- • -40°C = -40°F
- • K never negative
- • 1K = 1°C interval
