The joule (symbol: J) is the SI (International System of Units) derived unit of energy, work, or amount of heat. It is defined as the amount of energy transferred when a force of one newton is applied over a distance of one meter. The joule is a fundamental unit in physics and engineering, making it essential for various calculations involving energy and work.
The joule is standardized within the SI unit system, ensuring consistency across scientific and engineering disciplines. It is defined as follows: 1 J = 1 N·m = 1 kg·m²/s² This standardization allows for accurate calculations and conversions between joules and other units of energy, such as calories, kilowatt-hours, and electronvolts.
The joule is named after the English physicist James Prescott Joule, who made significant contributions to the study of energy and thermodynamics in the 19th century. His experiments demonstrated the relationship between heat and mechanical work, leading to the formulation of the law of conservation of energy. Over time, the joule has become a cornerstone in the fields of physics, chemistry, and engineering.
To illustrate the concept of joules, consider lifting a 1 kg object to a height of 1 meter. The work done against gravity can be calculated using the formula: Work (W) = Force (F) × Distance (d) Here, the force is equal to the weight of the object (mass × gravitational acceleration): W = (1 kg × 9.81 m/s²) × 1 m = 9.81 J Thus, lifting a 1 kg object to a height of 1 meter requires approximately 9.81 joules of energy.
Joules are widely used in various fields, including:
To use the joule unit converter tool effectively, follow these steps:
What is a joule? A joule is a unit of energy defined as the work done when a force of one newton is applied over a distance of one meter.

The Newton Meter per Second (N·m/s) is a unit of measurement that expresses torque or rotational force over time. It is a derived unit in the International System of Units (SI) that combines the unit of force (Newton) with the unit of distance (meter) and time (second). This unit is essential in various fields, including physics, engineering, and mechanics, where understanding the dynamics of rotational motion is crucial.
The Newton Meter per Second is standardized under the International System of Units (SI). The Newton (N) is defined as the force required to accelerate a one-kilogram mass by one meter per second squared. The meter is the base unit of length, and the second is the base unit of time. This standardization ensures consistency and accuracy in measurements across different scientific and engineering applications.
The concept of torque has been studied for centuries, with roots tracing back to ancient civilizations. However, the formal definition and standardization of the Newton Meter per Second emerged in the 20th century as the SI system was developed. The evolution of this unit reflects advancements in physics and engineering, allowing for more precise calculations and applications in modern technology.
To illustrate the use of the Newton Meter per Second, consider a scenario where a force of 10 N is applied to a lever arm of 2 meters. The torque can be calculated as follows:
[ \text{Torque (N·m)} = \text{Force (N)} \times \text{Distance (m)} ]
[ \text{Torque} = 10 , \text{N} \times 2 , \text{m} = 20 , \text{N·m} ]
If this torque is applied over a duration of 5 seconds, the value in Newton Meter per Second would be:
[ \text{Torque per Second} = \frac{20 , \text{N·m}}{5 , \text{s}} = 4 , \text{N·m/s} ]
The Newton Meter per Second is widely used in engineering and physics to quantify the effectiveness of motors, engines, and other mechanical systems. It is particularly relevant in applications involving rotational motion, such as in automotive engineering, robotics, and machinery design.
