Temperature Facts
Celsius scale was invented by Anders Celsius in 1742
Fahrenheit scale was created by Daniel Gabriel Fahrenheit in 1724
0°C = 32°F is the freezing point of water
100°C = 212°F is the boiling point of water
-40°C = -40°F is where both scales meet
Conversion Tips
For quick estimation: °F ≈ (°C × 2) + 30
Human body temperature is 37°C or 98.6°F
Room temperature is typically 20-22°C or 68-72°F
Use exact formulas for precise conversions
Understanding Temperature Scales
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.
Key Points
- •Named after Swedish astronomer Anders Celsius
- •100 degree intervals between freezing and boiling points
- •Used in science and most countries worldwide
- •More intuitive for everyday temperature references
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.

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