What does 1 MPa represent in pressure units?

1 MPa equals one million pascals (N/m²) and is used for measuring pressure and mechanical stress.

Why use foot water (4°C) as a pressure unit?

Foot water (4°C) expresses pressure as the hydrostatic pressure from a 1-foot column of water at 4°C, useful for hydraulic head and low-pressure evaluations.

Can this conversion apply to any water temperature?

No, the conversion is based on water density at 4°C, so results may vary if temperature differs.

Tips & Best Practices

Ensure input values reflect pressure measured consistent with definitions
Use this tool when working with hydraulic heads related to water at 4°C density
Confirm units before converting to avoid misinterpretation of results
Consider water temperature effects when precise measurements are needed

Limitations

The conversion assumes water density at exactly 4°C and may differ with temperature changes
Foot water (4°C) is suitable for low-pressure or hydraulic head contexts but not usual for representing very high mechanical stresses directly
For precise scientific work, variations in water density and temperature should be accounted for
