About Fahrenheit
The Fahrenheit scale is a temperature scale where the freezing point of water is 32°F and the boiling point is 212°F (at standard atmospheric pressure). It is primarily used in the United States.
Facts About Fahrenheit
- Water freezes at 32°F and boils at 212°F (at sea level)
- Named after German physicist Daniel Gabriel Fahrenheit (1686–1736)
- 180 degrees between freezing and boiling points
- Normal human body temperature is approximately 98.6°F
- Still used in the United States, Belize, and some Caribbean nations
Common Uses
- Weather forecasts in the United States
- Oven temperatures for cooking and baking
- Medical temperature monitoring in the US
- Industrial temperature controls in North America
- Historical scientific measurements
History
The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in 1724. He based the scale on three fixed points: 0°F (the freezing point of brine), 32°F (the freezing point of water), and 96°F (body temperature, which was later refined to 98.6°F). The scale became widely used in the English-speaking world before the metric system gained global adoption.
About Celsius
The Celsius scale, also known as the centigrade scale, is a temperature scale based on the freezing point of water at 0°C and the boiling point of water at 100°C (at standard atmospheric pressure).
Facts About Celsius
- Water freezes at 0°C and boils at 100°C (at sea level)
- Named after Swedish astronomer Anders Celsius (1701–1744)
- Used by most countries worldwide
- The official SI unit for temperature intervals is the degree Celsius
- Normal human body temperature is approximately 37°C
Common Uses
- Weather forecasts in most countries
- Scientific measurements and research
- Cooking and food preparation
- Medical temperature monitoring
- Climate and environmental studies
History
The Celsius scale was originally developed by Anders Celsius in 1742. Interestingly, Celsius initially proposed the reverse scale (0° for boiling and 100° for freezing), which was later inverted to the form we use today by Carl Linnaeus. The scale was renamed "Celsius" in 1948 to honor its creator.

Conversion Examples
Convert 1 Fahrenheit to Celsius
- Conversion Formula: °C = (°F - 32) ÷ 1.8
- Calculation: (1°F - 32) ÷ 1.8 = -17.2222°C
Convert 10 Fahrenheit to Celsius
- Conversion Formula: °C = (°F - 32) ÷ 1.8
- Calculation: (10°F - 32) ÷ 1.8 = -12.2222°C
Convert 100 Fahrenheit to Celsius
- Conversion Formula: °C = (°F - 32) ÷ 1.8
- Calculation: (100°F - 32) ÷ 1.8 = 37.7778°C
Convert 1,000 Fahrenheit to Celsius
- Conversion Formula: °C = (°F - 32) ÷ 1.8
- Calculation: (1,000°F - 32) ÷ 1.8 = 537.778°C
