How Temperature Conversion Works
Temperature scales relate to each other through fixed formulas rather than simple multiplication factors:
- Celsius to Fahrenheit: °F = (°C × 9/5) + 32
- Fahrenheit to Celsius: °C = (°F − 32) × 5/9
- Celsius to Kelvin: K = °C + 273.15
- Kelvin to Celsius: °C = K − 273.15
- Fahrenheit to Kelvin: K = (°F − 32) × 5/9 + 273.15
- Kelvin to Fahrenheit: °F = (K − 273.15) × 9/5 + 32
Common Temperature References in India
| Context | °C | °F |
|---|---|---|
| Normal body temperature | 37 | 98.6 |
| Mild fever | 38 | 100.4 |
| Indian summer peak (Delhi) | 45–48 | 113–118 |
| Pleasant winter (Mumbai) | 18–25 | 64–77 |
| Freezing point of water | 0 | 32 |
| Boiling point of water | 100 | 212 |
| Oil for deep frying (pakoras) | 170–180 | 338–356 |
| Tandoor oven | 250–480 | 480–900 |
When to Use Each Scale
Celsius (°C) is the standard in India for weather, cooking, and medical purposes. Fahrenheit (°F) is primarily used in the United States. Kelvin (K) is the SI base unit used in science and engineering — it starts at absolute zero (−273.15 °C), meaning there are no negative Kelvin values.
