What is a dekapascal?

A dekapascal (daPa) is an SI-derived pressure unit equal to 10 pascals that measures mechanical force per unit area.

Why use foot water (4°C) units?

Foot water (4°C) reflects pressure as the hydrostatic force from a one-foot water column at 4°C, useful in hydraulic and fluid system contexts.

Can this tool convert pressures for all temperatures?

No, the foot water unit is based on water density at 4°C, so temperature variations can influence the accuracy of conversions.
