**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.
