Pound

Definition: A pound (symbol: lb) is a unit of mass used in the imperial and US customary systems of measurement. The international avoirdupois pound (the common pound used today) is defined as exactly 0.45359237 kilograms. The avoirdupois pound is equivalent to 16 avoirdupois ounces.

History/origin: The pound descended from the Roman libra, and numerous different definitions of the pound were used throughout history prior to the international avoirdupois pound that is widely used today. The avoirdupois system is a system that was commonly used in the 13th century. It was updated to its current form in 1959. It is a system that was based on a physical standardized pound that used a prototype weight. This prototype weight could be divided into 16 ounces, a number that had three even divisors (8, 4, 2). This convenience could be the reason that the system was more popular than other systems of the time that used 10, 12, or 15 subdivisions.

Current use: The pound as a unit of weight is widely used in the United States, often for measuring body weight. Many versions of the pound existed in the past in the United Kingdom (UK), and although the UK largely uses the International System of Units, pounds are still used within certain contexts, such as labelling of packaged foods (by law the metric values must also be displayed). The UK also often uses both pounds and stones when describing body weight, where a stone is comprised of 14 pounds.

Gram

Definition: A gram (symbol: g) is a unit of mass in the International System of Units (SI). The definition of the gram is based on the kilogram, where a gram is one thousandth of a kilogram (the SI base unit of mass, currently based on an international prototype).

History/origin: Originally, a gram was defined as the absolute weight of pure water in a cubic centimeter at the temperature of melting ice (later 4 °C). The gram used to be a fundamental unit of mass as part of centimeter-gram-second systems of units up until the widespread adoption of SI, which uses kilograms as the base unit of mass. The gram was later redefined as one thousandth of a kilogram, the SI (meter-kilogram-second system of units) base unit of mass, which is currently (May 2018) based on the mass of a physical prototype of a specific alloy.

Current use: The gram is typically used to measure non-liquid ingredients used for cooking or groceries. Standards on the nutrition labels of food products often require the relative contents to be stated per 100 grams of the product.
