 Question 435648: how do we convert speed kps into metres per sec what formula do we use?Answer by Alan3354(30965)   (Show Source): You can put this solution on YOUR website!Hint: 1 kilo meter = 1000 meters (kilo = 1000 of whatever) Don't look for or try to memorize a formula, make use of the units. --------- eg: 5 km/sec = 5 km/sec * 1000 m/km 5*1000 km * meters/ km * sec = 5000 m/sec Notice that the km cancels and leaves meters/sec --------- If you do it "the wrong way", 5 km/sec / 1000 m/km = 5/1000 km*km/m*sec = 0.005 km^2/m*sec ??? the units make no sense. Use the units to confirm you made the correct conversion.
