10000
A huge number. Doses of vitamin D are usually measured in mcg (micrograms), not mg (milligrams). You would have to take eight hundred thousand 5000 IU tablets of vitamin D to be one hundred thousand MG. That's 800,000 5000 iu tablets of vitamin D = 100,000 mg. Even if you mean micrograms (mcg) it would require eight hundred (800) 5000 iu tablets of vitamin D to be 100,000 mcg. 800 5000 iu tablets of vitamin D = 100,000 mcg.
5000 IU
To convert mcg to mg: Divide by 1000 OR multiply by 0.001 OR move the decimal 3 places to the left (they all mean the same thing), so 500mcg = .5mg. Similarly, 1000mcg = 1mg, 2500mcg = 2.5mg, etc. AND to convert in the opposite direction, mg to mcg, multiply by 1000, so 3mg = 3000mcg, 1.5mg = 1500mcg, etc.
To convert 300 mg to 2000 IU you need to first convert the milligrams to micrograms (1,000 mcg is equal to 1 mg). Next, you need to determine what one IU represents.
Keep in mind that conversions from IU to mg are specific for each vitamin, so this formula/answer is only applicable for Vitamin D. You first have to convert the 2,000 IU into mcg. Each IU of Vitamin D is equal to 40 mcg, so you divide 2,000 by 40 which equals 50. Then you have to convert the mcg amount into mg which you do by dividing the mcg amount by 100. In this case 50 divided by 100, which equals 0.5, which means that 2,000 IU of Vitamin D is 0.5 mg
