( K cm/hr ) x ( 1 meter/100 cm ) x (1 km / 1,000 meters ) x (1 hr / 3,600 sec )= ( K x 1 x 1 x 1 ) / ( 100 x 1,000 x 3,600 ) (cm - m - km - hr) / (hr - cm - m - sec)= K / 360,000,000 km/secTake the number of cm per hour. Divide it by 360 millionto get the number of km per second.
73.5 km/hour = 73500 meters/hour = 73500/3600 meters/sec = 20.4166 meters/sec
( K cm/hr ) x ( 1 meter/100 cm ) x (1 km / 1,000 meters ) x (1 hr / 3,600 sec )= ( K x 1 x 1 x 1 ) / ( 100 x 1,000 x 3,600 ) (cm - m - km - hr) / (hr - cm - m - sec)= K / 360,000,000 km/secTake the number of cm per hour. Divide it by 360 millionto get the number of km per second.

Divided speed by 4, then add 2I.E 40km is 12m a sec
The speed of light in a vacuum is approximately 299,792,458 meters per second. To convert this to centimeters per hour, multiply by 3600 (the number of seconds in an hour) and then multiply by 100 (to convert meters to centimeters). The speed of light in centimeters per hour is roughly 10792528480000 cm/hr.
(350 mi/hr) x (1,609.344 meter/mi) / (3,600 sec/hr) = 156.46 meters/sec (rounded)
There are 1000 meters in a kilometer(1000 m) / (1 km). There are 3600 seconds in an hour, so (1 hr) / (3600 s). you can just multiply (1 km / hr)*[(1000 m) / (1 km)]*[(1 hr) / (3600 s)] to get 0.28 m/s.
(55 km/hr) x (1,000 m/km) / (3,600 sec/hr) = 15.2777 m/s (rounded, repeating)
(meters / sec) x (3600 sec / hr) / [(0.3048 meters / ft) x (5280 ft / mi)] 1.438*3600 / (0.3048*5280) = 3.2167144 mi / hr (mph)
(66 km/sec) x (3,600 sec/hr) = 237,600 km/hr
(9.81 meters/sec) x (3,600 sec/hr) / (1,609.344 meters/mile) = 21.944 mph (rounded)
