1m head of water is equivalent to 9.81kn/m2 or 9.81 kpa.
1 bar = 98.1kpa (approx 100) so 1m head = 0.1 bar, 10m head = 1 bar and so on.
convert 1bar to meter cube per hour
1 bar = 100,000 newton/square meter See related links for conversion calculator.
Those measure different things, so you can't convert that. Bar is a measure of pressure; meter is a unit of length.
The pressure of a liquid column of height h ("h meter liquid column) is: P = ρ*g*h [Bar], where ρ is the density of the liquid g is the gravitational acceleration (on Earth, in average 9.80665 m/s2)
