**Inches of water to atmospheres (technical)**

Atmospheres (technical) to inches of water

## Inches of water to atmospheres (technical) conversion formula

pressure(at) = pressure (inH2O) × 0.0025399295376097

**Example:**

Assume there are 17 inches of water. Shown below are the steps to express them in atmospheres (technical).

pressure(at) = 17 ( inH2O ) × 0.0025399295376097 ( at / inH2O )

pressure(at) = 0.043178802139365 at

or

17 inH2O = 0.043178802139365 at
