1g = 1000mg 500mg x 1g/1000mg = 0.5g
1g = 1000mg 10mg x 1g/1000mg = 0.01g
1g = 1000mg 20mg x 1g/1000mg = 0.02g
1g = 1000mg 10mg x 1g/1000mg = 0.01g
1g=1000mg Aabid
To convert .001g to mg you need to know that 1g is equal to 1000mg. So you want to setup a multiplication and division problem that will cancel out the sign of grams as you go along. .001g/1*1000mg/1g=1mg. When you take the .001g/1g, the g symbol goes away. You can times it by 1000mg/1g because 1000mg is equal to 1g.
1g
1g = 1000mg 1200mg>1000mg
1g = 1000mg 17g x 1000mg/g = 17000mg
1g = 1000mg 215g x 1000mg/g = 215000mg
1g = 1000mg
1000mg=1g
