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.

Frequently Asked Questions

Is 1 mmWC equal to a bar?

No, 1 mmWC = 9.80665 × 10⁻⁵ bar.
To put it in context:

• 1 bar = 10,197.162 mmWC (at standard gravity and 4°C water density)
• 1 mmWC = 0.0014 psi
• 1 mmWC = 9.80665 Pascal (Pa)
  

What is the formula for converting bar to mmWC?

To convert pressure from bar to mmWC:
1 bar = 10,197.162 mmWC
This is based on:

• Standard gravity: 9.80665 m/s²
• Water density at 4°C: 1000 kg/m³

How many mmWC are there in 1 kg/cm²?

1 kg/cm² = 10,000 mmWC
This is a common conversion used in hydraulic and pneumatic systems.

What is the unit mmWC used for?

mmWC (Millimeters of Water Column) is a low-range pressure unit derived from the hydrostatic pressure exerted by a 1 mm high water column at 4°C.

• 1 mmWC = 9.80665 Pa
• Often used in HVAC, cleanrooms, and differential pressure measurements.

How to convert mmWC to Pascals (Pa)?

Use the standard conversion factor:
1 mmWC = 9.80665 Pa
To convert, multiply mmWC by 9.80665.
Example: 50 mmWC = 50 × 9.80665 = 490.33 Pa
