How to Calculate Temperature Conversion
What is Temperature Conversion?
Temperature scales measure thermal energy. Celsius (°C) anchors to water's freezing (0°) and boiling (100°) points. Fahrenheit (°F) uses a different scale. Kelvin (K) starts at absolute zero — the coldest theoretically possible temperature.
Step-by-Step Guide
- 1C → F: multiply by 9/5 then add 32
- 2F → C: subtract 32 then multiply by 5/9
- 3K = C + 273.15 · R = F + 459.67
