What is an inch water (4°C) unit?

It is a small pressure unit representing the hydrostatic pressure exerted by a 1-inch column of pure water at 4 °C under standard gravity, typically used for low-pressure measurements.

Why convert inch water (4°C) to newton per square meter?

Converting to newton per square meter allows pressures measured in fine-resolution units to be expressed in standard SI units widely accepted in engineering and scientific fields.

Where is this conversion commonly applied?

It is frequently used in HVAC systems, fluid mechanics, weather measurement, laboratory manometer readings, and engineering stress analysis.
