GJ to ft·lb

gigajoule

• Definition: A gigajoule (GJ) is a unit of energy in the International System of Units (SI). It is equivalent to one billion joules.

• Symbol: The symbol for gigajoule is GJ.

• Usage: Gigajoules are commonly used to measure large quantities of energy, such as those found in electricity generation, heating, and fuel consumption.

foot pound

• Definition: A foot pound (ft·lb) is a unit of energy or work in the imperial system. It represents the amount of work done when a force of one pound is applied over a distance of one foot.

• Symbol: The symbol for foot pound is ft·lb.

• Usage: Foot pounds are often used in mechanical engineering and physics to describe torque and work done.

Origin of the gigajoule

• The term “gigajoule” is derived from the metric prefix “giga,” meaning one billion (10^9), combined with “joule,” named after the British physicist James Prescott Joule. The joule itself is a fundamental unit of energy in the SI system, establishing gigajoule as a standard for measuring large energy quantities.

Origin of the foot pound

• The foot pound has its origins in the imperial system of measurements, which dates back to the Middle Ages. The term combines “foot,” a unit of length, with “pound,” a unit of force. This unit has been widely used in the United States and the UK, particularly in engineering contexts.
