I want to make a comparison between the Vitamin E in two different dog foods. However one says 690mg per kilo and the other says 70.0iu/kg.
How can I 'convert' one of the amounts into the same measurement as the other so that they can be compared?
One thousand microgrammes (1000µg) is the same as one milligramme so 690mg is equal to 690,000µg and 70µg is equal to 0.07mg. So to compare, the one wi 690mg has almost 10,000 times as much Vitamin E than the other, which seems to be a huge difference.
