Convert the boiling point of cyclopropane at standard pressure to kelvins

Olenka [21]

Celsius to Kelvin conversion formula

The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15:

T(K) = T(°C) + 273.15

So to convert the boiling point of cyclopropane from degrees Celsius to kelvin:

T(K) = T(°C) + 273.15

T(K) = -33 + 273.15

T(K) = 240.15 K
