What is the difference between specific gravity and density?
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.
What is the metric unit for force divided by weight?
A weight is a force. If you divide a force by another force, you have a dimensionless unit, whether you use SI or any other system of units.A weight is a force.

What is the weight of glycol?
The weight of glycol will depend on the quantity!
What are the units of the coefficient of friction?
The coefficient of friction is a unitless value because it represents a ratio of the force required to move an object over a surface to the weight of the object. Since it is a ratio of two forces, it does not have any units associated with it.
Why specific gravity has no unit or dimensionless?
Because it's the ratio of two densities ... the density of the substance of interest to the density of water. In any ratio, the units of both quantities are the same, so the ratio winds up being a dimensionless number.
Which dimensionless quantity has unit?
If a quantity is "dimensionless", that means it has no units, and it's just a number.
Can a quantity have units but still be dimensionless?
No. "Dimensionless" means there are NO units involved.
What are dimensionless numbers?
the dimensionless numbers have the definition as that of dimensionless groups, and have all the properties which dimensionless groups have.
What is the rule of dimensionless quantity?
infinity
Does a dimensionless quantity have a unit?
No, a dimensionless quantity does not have a unit because it represents a pure number without any physical dimension. Examples of dimensionless quantities include ratios, proportions, and mathematical constants.
Can a quantity have constant value and be dimensionless?
Yes. Conversion factors will generally be dimensionless constants.
Can a quantity be dimensionless and have no units?
Yes, a dimensionless quantity is a quantity that does not have any physical dimensions or units. It is a pure number or ratio that represents a comparison between two quantities. Examples of dimensionless quantities include angles, ratios, and pure numbers like pi.
Can a quantity have units but still be dimension less give example?
Yes, a quantity can have units but still be dimensionless if the units cancel out when they are raised to the power of 0. For example, specific volume (volume per mass) has units of m^3/kg, but when you divide volume by mass, the units cancel out and it becomes dimensionless.
Can a quantity have unit and still be diamensionless?
No, a quantity cannot have units and still be dimensionless. The dimensions of a quantity are determined by its units, so if a quantity has units, it has dimensions. Dimensionless quantities are those without any units.
Are dimensionless quantity always unitless?
Yes, dimensionless quantities are always unitless. This means they do not have any physical units associated with them, and they represent a pure numerical value that is independent of any specific unit of measurement.
Is the magnitude of a vector quantity a dimensionless number?
Yes, the magnitude of a vector is a scalar.
What is the atomic weight of promethium?
145 (no units as atomic weight is dimensionless)
