This converter allows you to convert milliwatts [mW] to microwatts [µW] or microwatts [µW] to milliwatts [mW]. 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 milliwatt [mW] = 1,000 microwatts [µW]1 microwatt [µW] = 0.001 milliwatts [mW]

Convert milliwatts to microwatts

There are two simple ways to convert milliwatts [mW] to microwatts [µW]. In the first calculation method, the value in milliwatts [mW] is divided by 0.001. The second method multiplies the value in milliwatts [mW] by 1,000.

  • Microwatts [µW] = milliwatts [mW] ÷ 0.001
  • Microwatts [µW] = milliwatts [mW] * 1,000

Convert microwatts to milliwatts

Converting microwatts [µW] to milliwatts [mW] is easy and can be done in two ways. The first method involves multiplication, whereby the value in microwatts [µW] is multiplied by 0.001. The second variant is a division. Here, the value in microwatts [µW] is divided by 1,000.

  • Milliwatts [mW] = microwatts [µW] * 0.001
  • Milliwatts [mW] = microwatts [µW] ÷ 1,000

Pressure

Hectopascals, millibars, and bars are just a few examples of the many units of pressure. The pressure converter makes conversion a breeze and ensures that the results are accurate and precise.

Resistance

Electrical resistance is often expressed in ohms or kiloohms. However, it is also possible to use statohms or deciohms. The resistance converter is ideal for converting between different units of resistance.

Speed

While mph is used in the USA, km/h is the standard in Europe, and seafaring and aviation rely on knots. This speed converter is the perfect tool for accurately converting between various units of speed.
