长度单位换算表,各个长度单位的换算

1km=(1000)m
1m=(10)dm
1dm=(10)1cm
1cm=（10）mm
1mm＝（1000）μm
1μm＝（1000）nm

哪里有工程单位换算表？

压力单位
1 psi = 6.89 kPa 1 kgf/cm2 = 98.07 kPa
1 bar = 100 kPa 1 bar = 14.5 psi
1 mm mercury = 133.3 Pa
1 in mercury = 3.39 kPa
1 Torr = 133.3 Pa 1 ft water = 0.0298 bar
1 bar = 3.33 ft water 1 atmosphere = 101.3 kPa
1 cm water = 97.89 Pa 1 in water = 248.64 Pa
