What is a Fahrenheit?
Fahrenheit (°F) sets water's freezing at 32° and boiling at 212°, used in the US.
What is a Kelvin?
Kelvin (K) is the SI temperature scale starting at absolute zero (0 K = −273.15°C).
Real-world reference points
Room comfort sits near 21°C / 70°F; body temperature near 37°C / 98.6°F; water boils at 100°C / 212°F at sea level.
| Reference | Fahrenheit | Kelvin |
|---|---|---|
| Home freezer | -0.4 °F | 255 K |
| Comfortable room | 69.8 °F | 294 K |
| Body temperature | 98.6 °F | 310 K |
| Hot summer day | 104 °F | 313 K |
| Baking oven | 356 °F | 453 K |
| Water boils (sea level) | 212 °F | 373 K |
Mistakes to avoid with temperature conversions
- Doubling °C does not double °F — the scales have different zero points; use the formula, not proportion.
- Forgetting −40 is the one temperature where Celsius and Fahrenheit agree.
- Writing 'degrees Kelvin' — Kelvin is an absolute scale with no degree sign (300 K, not 300°K).
