단위환산. 0.510 in./ms to km/hr

inches/millisecond to kilometers/hour

 

---------------------------------------------------

 

1 in. = 2.54 cm = 0.0254 m = 0.0000254 km

1 ms = 0.001 s

 

 

0.510 in./ms × (0.0000254 km / 1 in.) × (1 ms / 0.001 s) × (3600 s / 1 hr)

= 0.510 × (0.0000254 / 1) × (1 / 0.001) × (3600 / 1)

= 46.6344 km/hr

---> 유효숫자 3개에 맞추면,

= 46.6 km/hr

 

 

: 46.6 km/hr
