Converting from Atmosphere (atm) to Inch of Water (inH₂0)

What is Atmosphere (atm)

An atmosphere (atm) is a unit of pressure commonly used in meteorology to measure air pressure. It is the average pressure at sea level and is equivalent to 1013.25 millibars.

What is Inch of Water (inH₂0)

An inch of water (inH₂0) is a unit of pressure used to measure small pressure differences. It represents the pressure exerted by a 1-inch column of water at standard gravity.

Conversion Formulas

The conversion formula from atmosphere (atm) to inch of water (inH₂0) is:

PinH₂0​=Patm​×406.7825

To convert from inch of water (inH₂0) to atmosphere (atm), the formula is:

Patm​=PinH₂0​×0.002458316

Examples

• Converting 4 atm to inH₂0:

4 atm=4×406.7825=1627.13 inH₂0

• Converting 12 inH₂0 to atm:

12 inH₂0=12×0.002458316=0.0294998 atm

• Converting 16 atm to inH₂0:

16 atm=16×406.7825=6508.519 inH₂0

With these conversion formulas and examples, you can easily convert between atmosphere and inch of water pressure units. Enjoy converting!
