This converter allows you to convert femtograms [fg] to micrograms [µg] or micrograms [µg] to femtograms [fg]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 femtogram [fg] = 10-9 micrograms [µg]1 microgram [µg] = 109 femtograms [fg]

Convert femtograms to micrograms

There are two simple ways to convert femtograms [fg] to micrograms [µg]. In the first calculation method, the value in femtograms [fg] is divided by 109. The second method multiplies the value in femtograms [fg] by 10-9.

  • Micrograms [µg] = femtograms [fg] ÷ 109
  • Micrograms [µg] = femtograms [fg] * 10-9

Convert micrograms to femtograms

Converting micrograms [µg] to femtograms [fg] is easy and can be done in two ways. The first method involves multiplication, whereby the value in micrograms [µg] is multiplied by 109. The second variant is a division. Here, the value in micrograms [µg] is divided by 10-9.

  • Femtograms [fg] = micrograms [µg] * 109
  • Femtograms [fg] = micrograms [µg] ÷ 10-9
