The Celsius scale, also known as centigrade, is based on 0° for the freezing point of water and 100° for the boiling point of water at standard atmospheric pressure.
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.
°F = (°C × 9/5) + 32
°C = (°F - 32) × 5/9
0°C = 32°F - The temperature at which water freezes under standard atmospheric pressure.
20-22°C = 68-72°F - The comfortable temperature range for most indoor environments.
37°C = 98.6°F - The average normal body temperature for healthy adults.
100°C = 212°F - The temperature at which water boils at sea level.
For a rough C to F conversion: double the Celsius value and add 30. For example, 20°C ≈ (20×2)+30 = 70°F (actual: 68°F).
-40°C equals -40°F - this is the only point where both scales intersect and show the same numerical value.
