What's the difference between atomiser ohm ratings (eg 1.8ohm or 2.1ohm)?

This is not something that you need to worry too much about but basically each cartomiser/atomiser/clearomiser has a resistance (ohms) rating. Different values can change the characteristics of the draw, vapour, flavour and can also affect battery life. If you have a variable power battery, then you already have a way to change the vaping characteristics - if you don't, then changing the ohm rating of the atomiser offers another way to experiment.

Lower Resistance Ratings (lower ohm numbers)
Atomisers with lower ohms ratings generally burn at a higher temperature (warmer vape) and produce more vapour and throat hit (all other things being equal and just the atomiser ratings being different). The extra heat of course requires extra power, so it's worth noting that batteries will drain faster when using lower resistance cartomizers. The additional heat can have an intensifying effect on the flavour too, so these are well suited to tobacco flavours which will generally withstand more heat, whilst fruit flavours may taste a little burnt as they are less forgiving. It really does come down to individual preference.

Higher Resistance Ratings (higher ohm numbers)
Atomisers with higher ohms ratings generally burn within a lower temperature range (cooler vape), and are usually a good starting point if you are unsure which to try first. 

You may find that only one or two types are available for your clearomiser/atomiser. If you do have a choice, then which type to use really does come down to individual preference. Experiment to find what suits you best.
