I have 3 unit conversions and they are not coming out right... what am I doing wrong if you can spot it:
1)1.64ly/min to SI Units:
1144.6W/m^2 but how do you get it with just the oringinal SI units...
2)2.3E27carats/parsec^3 to SI:
2.3E27carats/parsec^3 * (1kg/.0002carats) *( 1 parsec^3/2.938e49 m^3) = 3.91E-19 but is nothing like what google says !
3)642 furlongs per fortnight to SI:
642 furlongs/fortnight * (201.2m/1furlong)*(1/[24*60*60])*(201.2m/1furlong)=.107m/s?
