Constants Database

All data was taken from CODATA, you can enter their website for more information.

Also, you can take a look at the full list of constants.

Constants's Functions

The "name" parameter is the name of the constant in CODATA list. this name can be found in the complete list (link above)

val(name): returns constant's value
    example:
        val('conductance quantum') = > returns 7.748091729e-5

unit(name): returns constant's unit
    example:
        unit('speed of light in vacuum') = > returns m s^-1

uncertainty(name): returns constant's uncertainty
    example:
        uncertainty('Planck constant') = > returns 0.0

If any function returns the number zero with the type int, it means that the name you entered is wrong or not in the list. When the function needs to return the number zero, the type returned is float

Temperature Functions

The "number" parameter is the temperature value you want to convert

c_to_f(number)          Convert Celsius to Fahrenheit
f_to_c(number)          Convert Fahrenheit to Celsius
c_to_k(number)          Convert Celsius to Kelvin
k_to_c(number)          Convert Kelvin to Celsius
f_to_k(number)          Convert Fahrenheit to Kelvin
k_to_f(number)          Convert Kelvin to Fahrenheit
