Celsius to Fahrenheit conversion formula

Celsius (Centigrade)to

Fahrenheit [°F] = [°C] × 95 + 32
Kelvin [K] = [°C] + 273.15
Rankine [°R] = ([°C] + 273.15) × 95
Delisle [°De] = (100 − [°C]) × 32
Newton [°N] = [°C] × 33100
Réaumur [°Ré] = [°C] × 45
Rømer [°Rø] = [°C] × 2140 + 7.5

The next simple approximation works well within the range of normal weather temperatures [°F] = [°C] × 2 + 30 (or [°C] = ([°F] − 30) / 2) , underestimating by 6°F at −20°C and over by 4°F at 30°C.
