1000 mg = 1 g 1000 g = 1 kg ⇒ 1000 x 1000 mg = 1 kg ⇒ 1000000 mg = 1 kg ⇒ 150 mg = 150 ÷ 1000000 kg = 0.00015 kg
Since there are 1000 mg in 1 gram, and 1000 g in 1 kg, there are (1000 x 1000) mg in 1 kg, which is 1,000,000 mg in 1 kg. Or conversely, there are 0.000001 kg in 1 mg (that's 10-6 kg)
To convert mg per kg to percent, you first need to understand that 1 kg is equal to 1,000,000 mg. So, if you have a certain amount of mg per kg, you can divide that value by 10,000 to get the percentage. For example, if you have 500 mg per kg, you would divide 500 by 10,000 to get 0.05. To convert this to a percentage, you would multiply by 100 to get 5%.
1 part per million (ppm) is the same as 1 mg/kg and mg/L 1 mg=0.0001 g 1 kg=1000 g 1 mg/ 1 kg = 0.0001/1000 = 1/1,000,000 and, 1% = 0.01 = 1/100 so, to get from 1% (1/100) to 1 mg/kg (1/1,000,000), you must multiply by 10,000 (invert) this means 1% = 10,000 ppm or mg/kg or mg/L
You would use dimensional analysis. Your conversion factor is 1 kg = 1,000,000 mg. 1 mg . 1 kg = 0.000001 kg 1,000,000 mg
1 mg = 0.000001 kg (one-millionth of a kilogram) 1 mg is a milligram, or 1/1000 of a gram (much smaller) 1 kg is a kilogram, or 1000 grams (much larger)
250 mg/1 g = 250 mg/1000 mg = 250/1000 = 0.25 or 1/4
1 g = 1000 mg 1 kg = 1000 g ⇒ 1 kg = 1000 x 1000 mg = 1000000 mg ⇒ 544 kg = 544000000 mg
1000 mg = 1 g; 1000 g = 1 kg, therefore 1000 x 1000 or 1 000 000 mg/kg
1 mg = .001 Kg.Inversely, 1 Kg = 1000 mg
1 g = 1,000 mg 1 kg = 1,000,000 mg 185 kg = 185,000,000 mg
1 kg because 1 kg= 1,000,000 mg
