convert mM to uM

The capital M should be written as a lower case m.
There are 1,000 um in 1 mm.

To convert millimoles (mM) to micromoles (µM), you need to multiply the value in millimoles by 1000.

Here's the step-by-step process:

1. Take the value in millimoles (mM).
2. Multiply this value by 1000.

For example, if you have a concentration of 5 mM, the conversion would be:

5 mM x 1000 = 5000 µM

So, 5 millimoles (mM) is equivalent to 5000 micromoles (µM).
