I am currently studying A-level physics aqa spec and I was wondering how to covert between different units of the same quantity such as J, eV and kW h. Its on the specification and I cant really find anything on it probably because I'm just not looking properly. Does it have something to do with the prefixes?

1eV is basically 1.6x10‐¹⁹ J and the kW h one just use the prefix to convert it to W s is that's what your asking

1ev = 1.6x10^-16 J
KWh just means kilowatt hour, so one kilowatt for one hour (kilowatt is just 1000Watts)
Organic chemistry tutor on YouTube has some good videos
