Convert foot of water to pascal
Foot of water
The foot of water (ftH₂O) at 4 °C is a unit of pressure equal to the pressure exerted by a one-foot column of water at its maximum density, approximately 2,988.98 pascals. It is used in hydraulics, plumbing, and water supply engineering in the United States to express hydraulic head and pump pressures. One ftH₂O equals 12 inH₂O.
Pascal
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square metre (N/m²). It was adopted by the General Conference on Weights and Measures in 1971 and named after the French mathematician and physicist Blaise Pascal. Standard atmospheric pressure is approximately 101,325 Pa, and it is widely used in science, engineering, and meteorology.
