**Imperial British Gravitational**System - BG

**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 ≈ 6.674×10^{−}^{8} cm^{3}⋅g^{−}^{1}⋅s^{−}^{2}.

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 6.67430×10^{−}^{11} N⋅m^{2}/kg^{2}, 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/s^{2} on Earth.
