How do you convert pounds to kilograms?

The relationship between pounds and kilograms is defined by the conversion factor that 1 kilogram is approximately equal to 2.2 pounds. To find out how many kilograms correspond to a specific number of pounds, you can use the equation that expresses this relationship correctly: kilograms equal pounds divided by 2.2, or on a practical level, you can say pounds equal kilograms multiplied by 2.2.

Thus, when you want to convert pounds to kilograms, you need to take the number of pounds and divide it by 2.2 to arrive at the equivalent weight in kilograms. This makes it easier to understand that for every kilogram, there are about 2.2 pounds, leading to the justification that these units have a direct proportional relationship.

The formula presented in the correct answer accurately represents this conversion process by showing how the measurements relate to each other. This understanding is crucial when working with weights in different measurement systems, particularly in clinical settings where accurate conversions may impact patient care or medication dosages.
