例子

长度

1 in.= 25.4 mm

12 in.×25.4 = 304.8 mm

1 in.= 0.254 m

120 in. × .0254 =3.05 m

1 ft. =.3048 m

12 ft. × .3048 =3.68 m

1 mm= .03937 in.

100 mm × .02927 =3.94 in.

1 m= 39.37 in.

10 m × 39.37 =393.7 in.

1 m= 3.281 ft.

10 m × 3.281 =32.81 ft.

重量

1 lb.= .454 kg

10 lbs. × .454 = 4.54 kg

1 kg= 2.205 lbs.

10 kg × 2.205=22.05 22.05 lbs.

压力

1 psi= .069 bar

20,000 psi ×.069 = 1,380 bar

1 bar= 14.5 psi

1,000 bar ×14.5= 14,500 psi

流量

1 gpm=3.785 lpm

30 gpm × 3.785 = 113.55

1 lpm=.264 gpm

100 lpm ×.264= 26.4 gpm

力量

1 lb. (f) =4.44 N

100 lbs.(f) × 4.44= 444N

1 N= .2248 lbs .(f)

900 N × .2248 =202.32 lbs.(f)

动力

1 hp = .7457 kW

50 hp ×.7457 = 37.29 kW

1 kW= 1.341 hp

50kW × 1.341=67.05 hp

空气流量

1 cfm = .47195 l/s

10 cfm ×.47195 =4.72 l/s

1 l/s= 2.1189 cfm

10 l/sx× 2.1189 = 21.2 cfm
