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

To convert units from ft/sec to km/hr, you need to cancel out the units of ft and sec and replace them with km and hr respectively. Here is the correct conversion factor sequence:
1 ft/sec * (1 min/60 sec) * (1 hr/60 min) * (0.3048 m/ft) * (1 km/1000 m) * (hr/1) = km/hr
Let's break down the conversion step by step:
1. ft/sec to min/sec: Multiply by the conversion factor (1 min/60 sec) to cancel out the unit sec and convert to min.
2. min/sec to hr/sec: Multiply by the conversion factor (1 hr/60 min) to cancel out the unit min and convert to hr.
3. ft to m: Multiply by the conversion factor (0.3048 m/ft) to cancel out the unit ft and convert to m.
4. m to km: Multiply by the conversion factor (1 km/1000 m) to cancel out the unit m and convert to km.
5. Finally, multiply by (hr/1) to cancel out the unit hr.
So the correct conversion factor sequence is:
(1 ft/sec) * (1 min/60 sec) * (1 hr/60 min) * (0.3048 m/ft) * (1 km/1000 m) * (hr/1) = km/hr
Note that in the given sequence (ft/sec) x (sec/min) x (min/hr) x (m/ft) x (km/m), there's an error because the conversion factor (hr/1) is missing.
