What is the conversion factor sequence for units from ft./sec. to km./hr.?
Is (ft/sec) x (sec/min) x (min/hr) x (m/ft) x (km/m) correct?

1 in = 2.54 cm
1 m = 100 cm
1 cm = 0.01 m
1 in = 0.01 * 2.54
1 in = 0.0254 m
1 ft = 12 in
1 ft = 12 * 0.0254
1 ft = 0.3048 m
1km = 1000 m
1 m = 0.001 km
1ft = 0.3048 * 0.001
1ft = 0,0003048 km
1 h = 3600 s
1 s = 1 / 3600 h
1 ft / s = 0,0003048 / ( 1/3600 ) =
0,0003048 * 3600 =
1.09728
1 ft / s = 1.09728 km / h

You will find many sites where you can convert measuring units.
