Conversion between pounds and kilograms

Conversion from pound to kilogram: 1 pound =0.45359 kg.

First, the basic meaning of the pound

Pound (English: Pound) is a British unit of mass used in Britain and the United States, abbreviated as lb. After years of evolution in history, the quality system in Britain has also produced many different definitions of pounds, such as troy pound, tower pound, commercial pound, London pound, metric pound, international pound and so on. The most commonly used definition is international weight (international pound).

Two. Introduction to international units of measurement

International units of measurement include length (meter), mass (kilogram), time (second), current (ampere), thermodynamic temperature (Kelvin), amount of substance (mole) and luminous intensity (Candeira). The basic units are independent of each other in dimension, and there are many derived units, all of which are composed of basic units. There are only two auxiliary units, pure geometric units.

Auxiliary units can also constitute derived units. Various physical quantities are related to each other through equations describing natural laws and their definitions. The international system of units is formed according to the principle of consistency in the system of units of measurement, and its multiple and fractional units are formed by decimal system; The unit of multiple and fraction can only be composed of the prefix of SI, and its basic unit and definition can only be decided by the international metrology conference, and the special name and symbol of SI derivative unit can only be selected by the international metrology conference.

Three, the weight unit conversion matters needing attention

1. Confirm the physical quantity to be converted. Before converting weight units, you need to specify the physical quantities to be converted, such as mass and weight.

2. Confirm the original unit and target unit. When converting the weight unit, it is necessary to confirm the original unit and the target unit in order to correctly convert the unit.

3. Select the appropriate conversion coefficient. When converting weight units, you need to choose an appropriate conversion factor, such as kilograms, grams, milligrams, etc. Choosing the appropriate conversion coefficient can simplify the calculation process of unit conversion.

4. With the help of calculators and other tools, you can use calculators and other tools to improve the accuracy and efficiency of unit conversion.

5. Check the conversion result. After the weight unit is converted, it is necessary to check the accuracy of the conversion result to ensure that the conversion result conforms to the actual situation.
