This converter allows you to convert milligrams [mg] to nanograms [ng] or nanograms [ng] to milligrams [mg]. 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 milligram [mg] = 1,000,000 nanograms [ng]1 nanogram [ng] = 10-6 milligrams [mg]

Convert milligrams to nanograms

There are two simple ways to convert milligrams [mg] to nanograms [ng]. In the first calculation method, the value in milligrams [mg] is divided by 10-6. The second method multiplies the value in milligrams [mg] by 1,000,000.

  • Nanograms [ng] = milligrams [mg] ÷ 10-6
  • Nanograms [ng] = milligrams [mg] * 1,000,000

Convert nanograms to milligrams

Converting nanograms [ng] to milligrams [mg] is easy and can be done in two ways. The first method involves multiplication, whereby the value in nanograms [ng] is multiplied by 10-6. The second variant is a division. Here, the value in nanograms [ng] is divided by 1,000,000.

  • Milligrams [mg] = nanograms [ng] * 10-6
  • Milligrams [mg] = nanograms [ng] ÷ 1,000,000
