The modern 'avoirdupois pound' was standardized in 1959 to be exactly 0.45359237 kilograms, creating a bridge between the imperial and metric worlds. While the UK has officially adopted metric, the pound remains the cultural standard for body weight there (often via 'stones') and is the official unit of weight in the United States. pounds are commonly used in Body weight (US), Grocery produce (US), Baby birth weight, and Dumbbells and kettlebells (US), Boxing weight classes.

The ounce derives from the Roman 'uncia', meaning 'one twelfth', originally referring to 1/12th of a Roman pound. However, in the modern avoirdupois system used in the US and UK, an ounce is 1/16th of a pound. This unit is critical for precision in non-metric cooking and for measuring precious metals (though gold uses the 'troy ounce', which is slightly heavier). ounces are commonly used in Steak and meat portioning, Postal letter weights, Precious metals (Troy oz), and Liquid volume (fluid oz - different unit), Spices and seasonings.
