Heat deg days °c
WebThe Fahrenheit temperature range is based on setting the freezing point of water at 32 degrees, and boiling to 212 degrees. This means that boiling and freezing point are 180 degrees apart. Absolute zero is defined as -459.67°F. Celsius to Fahrenheit formula °F = °C * 1.8000 + 32.00 Why is converting Celsius to Fahrenheit so difficult?
