Historical Background of the Kilogram and Pound
The kilogram (kg) was originally defined in 1795 as the mass of one liter of water at its freezing point. It is now based on the Planck constant as defined by the International System of Units (SI). In contrast, the pound (lb) dates back to Roman times and was later standardized in the avoirdupois system used in the UK and USA.
This historical divergence between the metric and imperial systems is why understanding how to convert between them is essential for global interaction.
