There are two gravitational constants.
The 'real one', the Universal Gravitational Constant, is always known as G. As its name implies it works everywhere. *
The other one, acceleration due to gravity, is g. It is good only on our own planet.
Units of g are m s-2 . Units of G are m3 kg-1 s-2 .
*Some physicists are not quite sure about this. If one starts talking to you about "Planck-length gravity" you might want to remember an urgent appointment elsewhere.

Why do you measure using standard units instead of measuring with any kind of units?
Standard units are more commonly used than non standard units. Also, many of the conversion factors, such as the Universal Gravitational Constant or the Speed of Light, are in standard units and, if your measurements were not in appropriate units, you would need to convert.
Proof of universal gravitional law?
G is the universal gravitational constant. It is basically a conversion factor to adjust the number and units so they come out to the correct value. This is a universal constant so it is true everywhere.
Difference between electric forces and gravitational forces is that electrical forces include?
In case of electric force there are both repulsive and attractive. But in case of gravitational force, only attractive force. Electrical force between electric charges. Gravitational force between masses. In electric force we use a constant known as permittivity of the medium. But in gravitational force a universal constant known as Gravitational constant is used. Electrical force is very much greater than gravitational force.
What phase of the moon does it have the strongest gravitational pull?
The gravitational pull of the moon, on the earth, is almost a constant - whatever its phase.
What is the importance of your choice of units in expressing the value of the ideal gas law constant?
If any other units are used, the value will be different. --Depending on the units you chose the value of the constant differs
What is the approximate value of gravitational force?
The gravitational force between two objects depends on their distance, as well as the two masses involved. The value of the gravitational constant is 6.674 x 10^-11 (plus some units), in SI units. To get an actual force, multiply the two masses (in kilograms), divide by the square of the distance (in meters), and multiply that by the gravitational constant above. The answer is the force, in newton.
What are the dimensions and units of gravitational constant G?
The dimensions are [L^3M^(-1)T^(-2)] and the units are m^3 kg^(-1) s^(-2).
Who measured the gravitational constant G?
Cavendish measured the gravitational constant "G".
Why did Einstein have to find a gravitational constant?
The gravitational constant was found by Newton, not Einstein.
When was g the earth's gravitational constant calculated?
g, the force of the Earth's gravitational attraction, is not a constant.
Are gravitational constant and gravitational force the same thing?
No.
Why gravitational constant?
The gravitational constant was derived experimentally. Until recently, it was believed that it was a universal constant. However, developments in cosmological theories suggest the possibility that it is not a constant.
Who founded universal gravitational constant?
Sir. Isaac Newton discovered the formula with the universal gravitational constant.
What is the dimension of gravitation constant?
what is dimnsion of gravitational constant
What is the universal constant for gravity?
Gravity is proportional to the product of the masses, and inversely proportional to the square of the distance. The gravity constant is simply the proportionality constant. If you're calculating with all SI units, then the universal gravitational constant is 6.67 x 10-11newton-meter2/kilogram2
What is a measure of the gravitational force exerted on an abject?
Force gravitational = (mass of the object)(the gravitational constant) F=mg "g" is the gravitational constant, it is equal to 9.8 m/s^2
Why do you measure using standard units instead of measuring with any kind of units?
Standard units are more commonly used than non standard units. Also, many of the conversion factors, such as the Universal Gravitational Constant or the Speed of Light, are in standard units and, if your measurements were not in appropriate units, you would need to convert.
