5000ng is how many milligrams?

Answer 1

The nano- prefix means × 10^-9

The milli- prefix means × 10^-3

1 mg = 10^-3 g = 10^(6-9) g = 10^6 × 10^-9 = 10^6 ng

To convert mg to ng multiply by 10^6 = 1,000,000

→ To convert ng to mg divide by 10^6

→ 5000 mg = 5000 ÷ 1,000,000 ng = 0.005 ng

------------------------------------------------------------------------------------------------------------------------

Alternatively, manipulating the powers of 10:

5000 ng = 5000 × 10^-9 g

= 5000 × (10^-6-3) g

= 5000 × 10^-6 × 10^-3 g

= (5000 × 10^-6) mg

= 0.005 mg

Answer 2

n (nano) means ten to the power -9; milli means 10 to the power -3. Therefore, you need to shift by six powers of ten - move the decimal point 6 positions to the left. In other words, divide by a million.
