What does kilogram-force per square meter measure?

It measures pressure or normal stress as a force of one kilogram-force applied uniformly over one square meter.

Where is inch water (4°C) pressure unit commonly used?

It is widely used for low-pressure measurements in HVAC systems, gas line testing, filtration monitoring, and precise manometer readings.

Why might I convert kilogram-force/square meter to inch water (4°C)?

To translate older or regional pressure data given in gravitational metric units into a finer-resolution, modern low-pressure unit.

Are there any conditions to consider for accurate conversion?

Yes, the conversion depends on standard gravity and water temperature at 4°C for inch water measurements.
