Micromolar to Molar Calculator – Convert µM to molar M

To convert from micromolar to molar, multiply by 1 x 10^-6; to convert from molar to micromolar, multiply by 1,000,000.

Micromolar (μM) and molar (M) are units of concentration, with 1 μM equal to 1 x 10^-6 M.

Example Conversion:

For a concentration of 500 μM:

Convert to molar: 500 μM x 1.0E-6 M/μM = 0.0005 M

So 500 μM is equivalent to 0.0005 M.

Micromolar (µM) represents one millionth of a molar concentration, while Molar (M) is the standard unit of concentration in the International System of Units (SI).

µM to Molar Conversion Formula

The formula to convert µM to molar is:

M = µM ÷ 1,000,000

or

M = µM × 10^-6

This formula reflects the fact that one molar is equal to one million micromolar.

To convert 750 µM to M: 750 µM = 750 ÷ 1,000,000 = 0.00075 M

Alternatively, using scientific notation: 750 µM = 750 × 10^-6 = 7.5 × 10^-4 M

How do you convert micromolar to molar?

Converting micromolar to m involves a simple three-step process:

• Identify the micromolar concentration you want to convert.
• Divide the micromolar value by 1,000,000 (or multiply by 10^-6).
• Express the result in molar units (M).

Suppose you have a solution with a concentration of 2500 µM, and you need to express it in molar units.

Micromolar concentration: 2500 µM

Divide by 1,000,000: 2500 ÷ 1,000,000 = 0.0025

Express in molar units: 0.0025 M

Therefore, 2500 µM is equivalent to 0.0025 M.

What is 1 micromolar?

1 micromolar (1 µM) is a concentration unit that represents one millionth of a mole of solute per liter of solution. It’s a very dilute concentration often used in biochemistry and molecular biology for solutions of biomolecules like proteins or DNA.

To put this into perspective: 1 µM = 1 × 10^-6 M = 0.000001 M

Assume you have a 1 µM solution of caffeine (molecular weight ≈ 194.19 g/mol), it means there is 194.19 × 10^-6 g (or 0.19419 mg) of caffeine dissolved in 1 liter of solution.
