Most constants are in SI units, so you can do print '10 mile per minute is', 10*mile/minute, 'm/s or', 10*mile/(minute*knot), 'knots' The list is not meant to be comprehensive, but just a convenient list for everyday use. i(tdivisiontprint_functiontabsolute_importNi(tvalueiigyCxDgPKDgNgmCg4&k CgmBgeAg.Ag@@gY@g$@g?g{Gz?gMbP?gư>g& .>g-q=gV瞯sPlanck constants!Newtonian constant of gravitations standard acceleration of gravityselementary chargesmolar gas constantsfine-structure constantsAvogadro constantsBoltzmann constantsStefan-Boltzmann constants)Wien wavelength displacement law constantsRydberg constantg ̔?iXiiiiii g-C6*?s electron masss proton masss neutron masssatomic mass constantigN@iiimgv@g F%u?iiiiHg@iaig@g|=g1-]jABsstandard atmospheregj@ig@i(iii*gr?igHu@gfffffq@g?g#~j@g:H@gHz>i&gh㈵>cC`sX|jdkr(tj|t}n|jdkrLtj|}np|jdkrtj|ddd t}n<|jdkrtj|dd }ntd ||jdkr|t}ny|jdkr|}n^|jdkr!|td dd}n3|jdkrD|d d}ntd ||S(sA Convert from a temperature scale to another one among Celsius, Kelvin, Fahrenheit and Rankine scales. Parameters ---------- val : array_like Value(s) of the temperature(s) to be converted expressed in the original scale. old_scale: str Specifies as a string the original scale from which the temperature value(s) will be converted. Supported scales are Celsius ('Celsius', 'celsius', 'C' or 'c'), Kelvin ('Kelvin', 'kelvin', 'K', 'k'), Fahrenheit ('Fahrenheit', 'fahrenheit', 'F' or 'f') and Rankine ('Rankine', 'rankine', 'R', 'r'). new_scale: str Specifies as a string the new scale to which the temperature value(s) will be converted. Supported scales are Celsius ('Celsius', 'celsius', 'C' or 'c'), Kelvin ('Kelvin', 'kelvin', 'K', 'k'), Fahrenheit ('Fahrenheit', 'fahrenheit', 'F' or 'f') and Rankine ('Rankine', 'rankine', 'R', 'r'). Returns ------- res : float or array of floats Value(s) of the converted temperature(s) expressed in the new scale.
