Final answer:
To convert 0.540 inches/ms to kilometers per hour (km/h), you can use conversion factors to convert inches to meters, milliseconds to hours, and then convert meters per hour to kilometers per hour. The conversion is 0.00001371 km/h.
Step-by-step explanation:
To convert 0.540 inches/ms to kilometers per hour (km/h), we need to use conversion factors.
First, we convert inches to meters by multiplying by the conversion factor 0.0254 m/inch.
Then, we convert milliseconds to hours by dividing by the conversion factor 3.6 x 10^6 ms/hour.
Finally, we convert meters per hour to kilometers per hour by dividing by 1000.
So, the conversion would be:
0.540 inches/ms = (0.540 x 0.0254 m) / (1 x 3.6 x 10^6 h)
= 0.00001371 km/h.
