Temperature Facts
Fahrenheit scale was created by Daniel Gabriel Fahrenheit in 1724
32°F = 0°C is the freezing point of water
212°F = 100°C is the boiling point of water
-40°F = -40°C is where both scales meet
98.6°F = 37°C is normal human body temperature
Conversion Tips
For quick estimation: °C ≈ (°F - 30) ÷ 2
Freezing point: 32°F = 0°C
Room temperature: 68-72°F = 20-22°C

Understanding Temperature Scales
Fahrenheit Scale (°F)
The Fahrenheit scale sets the freezing point of water at 32°F and the boiling point at 212°F. It's primarily used in the United States and provides more granular temperature readings for weather.
Key Features
- •Named after Daniel Gabriel Fahrenheit (1686-1736)
- •180 degree intervals between freezing and boiling points
- •Commonly used in weather forecasts in the US
- •More precise for everyday temperature readings
Celsius Scale (°C)
The Celsius scale, also known as centigrade, is based on the freezing point (0°C) and boiling point (100°C) of water at standard atmospheric pressure. It's widely used worldwide and is the standard unit in the metric system.

Example Conversions
Fahrenheit to Celsius Examples
Convert 77°F to °C
°C = (77 - 32) × 5/9
°C = 45 × 5/9
°C = 45 × 0.556
°C = 25°C
Convert 212°F to °C
°C = (212 - 32) × 5/9
°C = 180 × 5/9
°C = 100°C (boiling point)
Celsius to Fahrenheit Examples
Convert 20°C to °F
°F = (20 × 9/5) + 32
°F = (20 × 1.8) + 32
°F = 36 + 32
°F = 68°F (room temperature)
Convert 37°C to °F
°F = (37 × 9/5) + 32
°F = 66.6 + 32
°F = 98.6°F (body temperature)
