ft·lb to GJ

foot pound

• Definition: A foot pound is a unit of energy or work, defined as the amount of energy transferred when a force of one pound acts on an object over a distance of one foot.

• Symbol: The symbol for foot pound is ft-lb or simply lb-ft.

• Usage: Foot pounds are commonly used in the context of torque, mechanical work, and energy in various engineering and construction applications.

gigajoule

• Definition: A gigajoule is a unit of energy equal to one billion joules, used to measure large amounts of energy.

• Symbol: The symbol for gigajoule is GJ.

• Usage: Gigajoules are often used in fields like electricity generation, heating, and fuel consumption to quantify energy outputs or requirements.

Origin of the foot pound

• The foot pound originated from the Imperial system of measurements, which has its roots in the British system. It combines the foot, a linear measurement, with the pound, a unit of force or weight. The concept of work, represented by the foot pound, can be traced back to early mechanical principles and was widely adopted during the Industrial Revolution.

Origin of the gigajoule

• The gigajoule is part of the International System of Units (SI) and derives from the joule, which is named after the English physicist James Prescott Joule. The prefix “giga,” meaning billion, comes from the Greek word for giant. The gigajoule is used globally in scientific and engineering contexts, evolving with advancements in technology and energy measurement.
