To convert from Fahrenheit to Celsius in your head you can subtract 30 from the Fahrenheit figure and halve the result. This is only a rough estimate and only to be used for values typically found in weather temperatures.

Absolute Zero -459.67℉-273.15℃
Parity -40℉ -40℃
Zero 0℉ -17.78℃
Freezing point 32℉ 0℃
Body Temperature 98.6℉ 37℃
Boiling point 212℉ 100℃

Fahrenheit

Fahrenheit is a thermodynamic temperature scale, where the freezing point of water is 32 degrees Fahrenheit (℉) and the boiling point 212℉ (at standard atmospheric pressure). This puts the boiling and freezing points of water exactly 180 degrees apart. Therefore, a degree on the Fahrenheit scale is 1/180 of the interval between the freezing point and the boiling point of water. Absolute zero is defined as -459.67℉.

A temperature difference of 1℉ is the equivalent of a temperature difference 0.556℃.

Celsius

Although initially defined by the freezing point of water (and later the melting point of ice), the Celsius scale is now officially a derived scale, defined in relation to the Kelvin temperature scale.

Zero on the Celsius scale (0℃) is now defined as the equivalent to 273.15K, with a temperature difference of 1 deg C equivalent to a difference of 1K, meaning the unit size in each scale is the same. This means that 100℃, previously defined as the boiling point of water, is now defined as the equivalent to 373.15K.

The Celsius scale is an interval system but not a ratio system, meaning it follows a relative scale but not an absolute scale. This can be seen because the temperature interval between 20℃ and 30℃ is the same as between 30℃ and 40℃, but 40℃ does not have twice the air heat energy of 20℃.

A temperature difference of 1 deg C is the equivalent of a temperature difference 1.8°F.
