This converter allows you to convert milligrams [mg] to micrograms [µg] or micrograms [µg] 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.
Convert milligrams to micrograms
There are two simple ways to convert milligrams [mg] to micrograms [µg]. In the first calculation method, the value in milligrams [mg] is divided by 0.001. The second method multiplies the value in milligrams [mg] by 1,000.
- Micrograms [µg] = milligrams [mg] ÷ 0.001
- Micrograms [µg] = milligrams [mg] * 1,000
Convert micrograms to milligrams
Converting micrograms [µg] to milligrams [mg] is easy and can be done in two ways. The first method involves multiplication, whereby the value in micrograms [µg] is multiplied by 0.001. The second variant is a division. Here, the value in micrograms [µg] is divided by 1,000.
- Milligrams [mg] = micrograms [µg] * 0.001
