Depends on what units you are talking about :)
1000
1g=1000mg When converting units, put what kind of units you want (grams) on top, and what kind of units you have (mg) on bottom. so.. 500mg x (1g) = 0.5 grams 1000mg mg will cancel leaving your units in grams.
500 mg = 0.5 g
500 mg = 0.0005 kg
500
500 mg = 7.71616 gr
