HOW MANY feet of water is 977 millibars?

Answer 1

1 millibar = .977 bar .977 bar = 97700 pa (1 bar = 10^5 pa) Pascals is an SI unit, so we can do the rest of the calculation in SI units.

For a liquid, such as water, pressure = rho * g * h (where rho is density of the liquid, g is the acceleration due to gravity, and h is the height of the liquid). p (pa) = rho (kg/m^3) * g (kg m/sec^2) * h (m) 97700 pa = 1000 kg/m^3 * 986 m/sec^2 * h (m) h = 9.908m * 3.281 m/ft h = 32.51 ft of water
