Temperature Conversion Formulas:

℉ = ℃×9/5 + 32 | ℃ = (℉-32)×5/9 | K = ℃ + 273.15

Results shown with 2 decimal places (switch to 4 decimals for scientific use)

*SI base unit: Kelvin (K); Celsius = K - 273.15; Fahrenheit = common in US/UK

International standard: weather, cooking, daily use (0℃ = freezing, 100℃ = boiling)

Frequently Asked Questions

About temperature units and conversions

Why are the Celsius-Fahrenheit conversion formulas structured that way?

The formulas originate from Fahrenheit's historical definition and metric standardization:

  • Fahrenheit's original scale set water's freezing point at 32℉ and boiling point at 212℉ (180-degree interval)
  • Celsius uses a 100-degree interval between water's freezing (0℃) and boiling (100℃) points
  • Conversion ratio: 1℃ = 1.8℉ (9/5) + offset (32℉) → ℉ = ℃×9/5 + 32
  • Reverse conversion: Subtract the offset first, then divide by 1.8 → ℃ = (℉-32)×5/9
