Calculators

Calculates the approximate wattage of a light source based on its lumen output and efficiency (lumens per watt). This helps estimate energy consumption.

Converts between different units of radiation, including absorbed dose and equivalent dose.

This calculator converts between various units of force, including Newtons, dynes, pounds-force, and kilogram-force.

Calculates the air-fuel ratio (AFR), which represents the mass ratio of air to fuel in an internal combustion engine. This ratio is crucial for efficient combustion and emissions control.

Calculates the momentum of an object, which is the product of its mass and velocity.

Calculates the change in position of an object, often using kinematic equations (SUVAT).

Calculates the recommended turbocharger size based on engine displacement, desired horsepower, and redline RPM.

Calculates speed, distance, or time based on the other two values.

Calculates the tension in a string, cable, or similar object based on the mass and acceleration.

Calculates the total horizontal distance covered by a projectile before landing, considering initial velocity, launch angle, and the effect of gravity.
