How to Convert US Units to Micrograms

There are one million metric micrograms in a metric gram. In scientific notation, you can write "one million" as 1 x 10^6, that is, as a 1 with six zeros after it -- 1,000,000. The U.S. system of unit measurements uses ounces and pounds to express weight, one ounce being one-sixteenth of a pound and one pound representing 16 ounces. Though scientists use the metric system almost exclusively, you might be interested in learning how U.S. pounds and ounces compare to their very tiny counterpart in the metric system, the microgram.

Instructions

- 1
  Multiply your value in pounds by 453.59 using a scientific calculator to convert the value to grams. For example, 0.03 x 453.59 = 13.607. A value of 0.03 pounds equals 13.61 grams.
- 2
  Multiply your answer by 1 x 10^6 using a scientific calculator to convert the value to micrograms. For example, 13.607 x 1 x 10^6 = 1.3607 x 10^7. A value of 0.03 pounds, or 13.61 grams, equals 1.36 x 10^7 micrograms.
- 3
  Multiply your value in ounces by 28.35 using a scientific calculator to convert the value to grams. For example, 3 x 28.35 = 85.05. A value of 3 ounces equals 85.05 grams.
- 4
  Multiply your answer by 1 x 10^6 using a scientific calculator to convert the value to micrograms. For example, 85.05 x 1 x 10^6 = 8.505 x 10^7. A value of 3 ounces, or 85.05 grams, equals 8.51 x 10^7 micrograms.
