Historical background
The pound’s history traces back to Roman times, where "libra pondo" (meaning "a pound by weight") referred to a mass of about 327 grams. Fast forward to medieval England, the avoirdupois pound (the one we use today) standardized at 7,000 grains. Meanwhile, the gram emerged during the French Revolution as part of the metric system, designed to simplify trade with base-10 units. Imagine arguing with a baker in 1795 about how much a "gramme" should weigh!
