Pounds to Kilogram ( lbs to kg ) Relation

Both Pound (lb) and Kilogram(kg) are units of measurement of weight or mass. A pound(lbs) is an imperial unit of mass or weight. Likewise, after the adoption of the SI system in the year 1959, the unit kilogram has been adopted as the unit of measurement of weight.

However, when we examine the technicalities behind both the terms, it remarkably becomes more complex and hard to differentiate between the two units. 1 pound (lb) is stated to be 0.454 times lighter than 1 kg (represented as kg). Thus, one pound of mass is equal to 0.454 kg.
