# What is the gravitational constant in English units?

The Imperial British Gravitational System - BG
The three base units in the Imperial system are foot, second and pound-force. In the BG system the mass unit is the slug and is defined from the Newton's Second Law (1).

Accordingly, what is the unit for the gravitational constant?

The dimensions assigned to the gravitational constant are force times length squared divided by mass squared; this is equivalent to length cubed, divided by mass and by time squared: In SI base units, this amounts to meters cubed per kilogram per second squared: In cgs, G can be written as G ≈ 6.674×108 cm3⋅g1⋅s2.

Furthermore, what does 9.81 mean? It means, for acceleration of 9.81 (m/s^2), the velocity will increase by 9.81 meter/sec. It means, if you let a body fall freely (on earth), then this is the rate at which it will gain in speed towards the ground. It's called the acceleration due to gravity.

In this manner, what is the universal gravitational constant in English units?

The gravitational constant, called. in physics equations, is an empirical physical constant. It is used to show the force between two objects caused by gravity. The gravitational constant appears in Isaac Newton's universal law of gravitation. is about 6.67430×1011 N⋅m2/kg2, and is denoted by letter .

What is the value of G?

In the first equation above, g is referred to as the acceleration of gravity. Its value is 9.8 m/s2 on Earth.
