# Millimeter of Water Column (mmWC) to Bar Pressure Unit Conversion Calculator

This calculator allows you to convert pressure values from millimeters of water column (mmWC) to bar, which is essential for various instrumentation, HVAC, and industrial applications.

**Definition: Millimeter of Water Column (mmWC)**

A millimeter of water column (symbol: mmWC or mmH₂O) is a unit of pressure that represents the pressure exerted by a 1 mm high column of water at 4°C under standard gravity. It is often used in low-pressure systems such as HVAC, gas pressure measurements, and water treatment.

**Definition: Bar**

A bar is a metric unit of pressure, defined as 100,000 Pascals (Pa). While not an SI unit, it is commonly used in meteorology and engineering, especially for high-pressure measurements.

**Formula for mmWC to Bar Conversion:**

**Pressure in Bar = Pressure in mmWC ÷10197.16**

**How to Convert mmWC to Bar: Example Calculation**

Suppose you have a pressure of 10197.16 mmWC.

To convert it to bar:

10197.16 mmWC ÷10197.16=1 bar

So, 10197.16 mmWC is equal to 1 bar.
