Remark

m(meter)

= 1inch = 0.025m(25.4mm), 1mile = 1609m(1.609km)

 

kg(kilogram)

= 1pound(lb) = 0.4536kg

 

Pa(Pascal)

= 1bar =100kPa, 1kgf / = 98.066kPa, 1pound per square inch(p.s.i or lbf / in2 ) = 6.895kPa

 

m/s(meter per second)

= 1km per hour (km/h) = 0.27778m/ s, 1mile per hour(m.p.h) = 0.470m /s(1.60935km/h)
