This converter allows you to convert troy ounces [oz.tr.] to micrograms [µg] or micrograms [µg] to troy ounces [oz.tr.]. 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 troy ounce [oz.tr.] = 31,103,476.8 micrograms [µg]1 microgram [µg] ≈ 3.215 * 10-8 troy ounces [oz.tr.]

Convert troy ounces to micrograms

There are two simple ways to convert troy ounces [oz.tr.] to micrograms [µg]. In the first calculation method, the value in troy ounces [oz.tr.] is divided by the rounded conversion factor of 3.215 * 10-8. The second method multiplies the value in troy ounces [oz.tr.] by 31,103,476.8.

  • Micrograms [µg] ≈ troy ounces [oz.tr.] ÷ (3.215 * 10-8)
  • Micrograms [µg] = troy ounces [oz.tr.] * 31,103,476.8

The calculation method with a rounded conversion value is more suitable for rough conversions from troy ounces [oz.tr.] to micrograms [µg], as the calculation result may contain rounding errors. Therefore, the variant with the exact conversion factor is more suitable.


Convert micrograms to troy ounces

Converting micrograms [µg] to troy ounces [oz.tr.] is easy and can be done in two ways. The first method involves multiplication, in which the value in micrograms [µg] is multiplied by the rounded conversion factor of 3.215 * 10-8. The second variant is a division. Here, the value in micrograms [µg] is divided by 31,103,476.8.

  • Troy ounces [oz.tr.] ≈ micrograms [µg] * 3.215 * 10-8
  • Troy ounces [oz.tr.] = micrograms [µg] ÷ 31,103,476.8

The rounded conversion value can cause rounding errors, resulting in inaccurate calculation results. To ensure that the conversion from micrograms [µg] to troy ounces [oz.tr.] produces the most accurate calculation result possible, the conversion should be performed using the exact conversion factor.
