Conversion of pound and kilogram, kilograms in pneumatic valves and pounds of conversion

Conversion of pound and kilogram, kilograms in pneumatic valves and pounds of conversion


conversion of pound and kilogram, kilograms and conversion between pounds:



kg ( Kg is also called kg) Is to measure the quality of legal measurement units in the international system of units, pounds ( lb） Is British and American English used by the quality unit, are used as weight measuring code. So, how much one pound is equal to the cost? How much kg is 1 pound?



according to the international metric conversion standard, 1 pound = 453. 6 g, and 1 kg = 500 grams, so 1 pound = 0. 972 jins, namely 1 pound = 0. 4536 kilograms.



the commonly used method of weight reduction:





1 kg = 0. 001 metric tons ( Or & other T & throughout; )

1 oz = 437. 5 = 28. 350 grams of



1 kg = 1000 g

1 pound = 16 oz = 0. 4536 kg



1 kg = 1000000 mg

1 beauty = 100 - pound = 45. 359 kg



1 kg = 1000000000 micrograms of

1 hundredweight = = 50 112 pound. 802 kg



1 kg = 2 jins

1 ton = 2000 pound = 0. 9072 metric tons of



1 kg = 20 two

1 tons = 2240 pound = 1. 0161 metric tons of




pneumatic valve in kg, and conversion of pounds:



because of pneumatic valves have different standards, some with pneumatic valve pressure pounds ( 类) Said, some with kg ( PN） Said, the pneumatic valve conversion in pounds and kilograms? Kg said PN is a code, related to the pressure is the nominal pressure, domestic pneumatic valve usually use pounds ( 类) For the nominal pressure of the pneumatic valve represents American standard, kg ( PN） And pounds ( 类) Said the pressure method, is not the same place is that they represent different pressure corresponding to the reference temperature.

note: kg ( PN） European system refers to the corresponding pressure under 120 ℃, and the pound ( 类) American standard is refers to the corresponding pressure under 425 ℃. So in engineering swap can't simply stress conversion.

example: CLass300 # solely using pressure conversion should be 2. 1 mpa, but if consider to use temperature, its corresponding pressure is increased, according to the temperature of the material withstand voltage test is equal to 5. 0MPa。
