For example, "The package weighs 5 kg."（这个包裹重5公斤。） However, note that "Kg" with a capital "K" is less common but still acceptable, though the lowercase "kg" is the internationally recognized standard.

四、公斤与其他计量单位的转换

To convert between kilograms and other units, you can use conversion factors. For example, to convert from kilograms to pounds, multiply by 2.20462. To go from pounds to kilograms, divide by the same number. Its important to remember these conversions when dealing with international measurements.

五、公斤的科学背景

The kilogram is defined by a physical artifact, the International Prototype Kilogram (IPK), which is a platinum-iridium cylinder stored at the International Bureau of Weights and Measures (BIPM) in France. This ensures worldwide consistency in the definition of the unit.
