Calculate with the Gravitational Constant

Calculators for the gravitational acceleration and the weight from gravitational constant, mass and radius. The gravitational constant G is a fundamental physical constant with a fixed value, which is known to four decimal places, G = 6.6743 * 10^-11 m³ / ( kg * s² ). From the mass and radius of a planet or other body, with this constant the gravitational acceleration on that can be calculated. With a second mass, the weight force between the two bodies can be calculated.
