Gram/cm³
Definition: The gram per cubic centimeter (symbol: g/cm³ or g/cc) is a unit of density in the CGS (centimeter-gram-second) system. It is exactly equivalent to 1,000 kg/m³.
History/origin: Before the SI system became the global standard, the CGS system was widely used in science. In this system, pure water at 4°C was the benchmark, having a density of exactly 1 g/cm³.
Current use: It remains highly popular in chemistry, medicine, and material sciences because it provides a convenient, small-scale number for the density of common solids and liquids.
Pound/ft³
Definition: The pound per cubic foot (symbol: lb/ft³) is an imperial and US customary unit of density. It is defined as one pound of mass per cubic foot of volume.
History/origin: This unit is derived from the historic avoirdupois pound and the international foot, which were the standard weights and measures in the British Empire.
Current use: It is predominantly used in the United States and the UK for construction, civil engineering, and HVAC (heating, ventilation, and air conditioning) to calculate the density of concrete, wood, and air.

Did You Know?
- Osmium is the densest naturally occurring element on Earth, with a staggering density of about 22.59 g/cm³. A football-sized chunk of Osmium would weigh over 120 kilograms!
- The density of Earth's atmosphere at sea level is approximately 0.0765 lb/ft³ (1.225 kg/m³). It might seem light, but the total weight of the atmosphere is about 5.5 quadrillion tons!
