4500 milligrammes = 4.5 grammes
0.001 g = 1 mg
1,000 mg = 1 g 6,500 mg = 6.5 g
48 g 19 mg is equal to 48.019 g.
1000 mg = 1 g 1 mg = 10-3 g = 0.001 g 500 mg = 0.5 g
0.015 g is equal to 15 mg.
0.4 g is equivalent to 400 mg. Therefore, two 200 mg capsules equal 0.4 g.
4.5 grams (prefix mili- in the metric system represents 1/1000 of any basic unit: opposite is kilo- which is 1000 times the basic unit - 1 kg (kilogram) = 1000 grams = 1 000 00 mg).
580 mg is greater than 5 g. This is because 1 g is equal to 1000 mg. Therefore, 5 g is equal to 5000 mg, making 580 mg less than 5 g.
0.045 g x (1000 mg / 1 g) = 45 mg
1,000 milligrams (mg) = 1 gram (g) ... (that's what "milli-" means)
