This converter allows you to convert carats [ct] to nanograms [ng] or nanograms [ng] to carats [ct]. 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 carat [ct] = 2 * 108 nanograms [ng]1 nanogram [ng] = 5 * 10-9 carats [ct]

Convert carats to nanograms

There are two simple ways to convert carats [ct] to nanograms [ng]. In the first calculation method, the value in carats [ct] is divided by 5 * 10-9. The second method multiplies the value in carats [ct] by 2 * 108.

  • Nanograms [ng] = carats [ct] ÷ (5 * 10-9)
  • Nanograms [ng] = carats [ct] * 2 * 108

Convert nanograms to carats

Converting nanograms [ng] to carats [ct] is easy and can be done in two ways. The first method involves multiplication, whereby the value in nanograms [ng] is multiplied by 5 * 10-9. The second variant is a division. Here, the value in nanograms [ng] is divided by 2 * 108.

  • Carats [ct] = nanograms [ng] * 5 * 10-9
  • Carats [ct] = nanograms [ng] ÷ (2 * 108)
