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

This calculator allows you to convert pressure values from bar to millimeters of water column (mmWC), which is useful in various instrumentation and process control applications.

**Definition: Bar**

A bar is a metric unit of pressure, defined as 100,000 Pascals. It is not an SI unit, but it is widely used in various industries, especially in meteorology and engineering.

**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 commonly used in HVAC systems, gas pressure measurements, and low-pressure systems.

**Formula for Bar to mmWC Conversion:**

**Pressure in mmWC=Pressure in Bar×10197.16**

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

Suppose you have a pressure of 1 bar.

To convert it to millimeters of water column (mmWC):

1 bar×10197.16=10197.16 mmWC

So, 1 bar is equal to 10197.16 mmWC.

**Quick Reference Conversion Table for Bar to mmWC**
