Conversion of pounds to kilograms, conversion of kilograms to pounds in valves

Author:


The kilogram ( kg, also known as the kilogram) is the legal unit of measurement for measuring mass in the International System of Units. The pound (lb) is the imperial mass unit used in the United Kingdom and the United States. They are both used as codes for weight measurement. So, how many kilograms is equal to 1 pound? 1 pound equals how many kilograms?

The kilogram ( kg, also known as the kilogram) is the legal unit of measurement for measuring mass in the International System of Units. The pound (lb) is the imperial mass unit used in the United Kingdom and the United States. They are both used as codes for weight measurement. So, how many kilograms is equal to 1 pound? 1 pound equals how many kilograms?

According to the international measurement conversion standard, 1 pound = 453.6 grams, and 1 pound = 500 grams, so 1 pound = 0.972 pounds, that is, 1 pound = 0.4536 kilograms.

Commonly used weight conversion methods:

1 kilogram = 0.001 metric ton (or "ton")

1 ounce = 437.5 grains = 28.350 grams 

1 kilogram = 1,000 grams

1 pound = 16 ounces = 0.4536 kilograms 

1 kilogram = 1,000,000 milligrams

1 cwt = 100 pounds = 45.359 kilograms

1 kilogram = 1,000,000,000 micrograms

1 hundredweight = 112 pounds = 50.802 kilograms

1 kilogram = 2 pounds 

1 US ton = 2000 pounds = 0.9072 metric tons

1 kilogram = 20 taels

1 ton = 2240 pounds = 1.0161 metric tons

 

Conversion of kilograms and pounds in valves:

Because the standards of valves are different, some valve pressures are expressed in pounds (class), and some are expressed in kilograms (PN). So how to convert pounds and kilograms in valves? Kilogram PN is a code related to pressure. It is the nominal pressure commonly used in domestic valves. Pound (class) is the nominal pressure represented by American standard valves. Kilogram (PN) and pound (CLass) are both methods of expressing pressure. , the difference is that the pressure they represent corresponds to the reference temperature.

 

Note: The European system of kilograms (PN) refers to the pressure corresponding to 120℃, while the American standard of pounds (CLass) refers to the pressure corresponding to 425℃. Therefore, we cannot simply perform pressure conversion in engineering interchange.

Example: CLass300# should be 2.1MPa simply based on pressure conversion, but if the operating temperature is taken into account, its corresponding pressure will increase. According to the temperature and pressure test of the material, it is equivalent to 5.0MPa.
