Fahrenheit (°F)
Definition: Fahrenheit is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit. On this scale, water freezes at 32°F and boils at 212°F.
History/origin: Daniel Fahrenheit used a brine solution (ice, water, and ammonium chloride) to set his 0° point and estimated human body temperature to be around 96°F (later corrected to 98.6°F).
Current use: Fahrenheit is primarily used in the United States, its territories, and several Caribbean nations (like the Bahamas and Belize) for everyday temperature and weather measurements.
Celsius (°C)
Definition: Celsius, also known as centigrade, is a scale and unit of measurement for temperature. It is based on 0° for the freezing point of water and 100° for the boiling point of water at standard atmospheric pressure.
History/origin: Named after the Swedish astronomer Anders Celsius (1701–1744). Before 1948, the scale was widely known as "centigrade" from the Latin "centum" (100) and "gradus" (steps).
Current use: Celsius is the most widely used temperature scale in the world today. It is the official scale for almost all countries and is used in science, medicine, and weather reporting everywhere except the US.
Fahrenheit (°F) to Celsius (°C) Conversion Table
| Fahrenheit (°F) [f] | Celsius (°C) [c] |
|---|---|
| 0.01 f | 0.01 c |
| 0.1 f | 0.1 c |
| 1 f | 1 c |
| 2 f | 2 c |
| 3 f | 3 c |
| 5 f | 5 c |
| 10 f | 10 c |
| 20 f | 20 c |
| 50 f | 50 c |
| 100 f | 100 c |
| 1000 f | 1000 c |
How to Convert Fahrenheit (°F) to Celsius (°C)
1 f = 1 c
1 c = 1 f
Example: convert 15 f to c:
15 f = 15 × 1 c = 15 c
Did You Know?
- Fahrenheit is the primary temperature scale used in the United States. To remember the difference: 0°F is very cold, and 100°F is very hot for a human, making it a very human-centric scale!
- Did you know? The Celsius scale was originally designed in reverse! Anders Celsius initially set 0° as the boiling point of water and 100° as the freezing point. It was flipped to its current form after his death.
