What is the meaning of a frame of reference where $c=1$ ?
Are these the so called natural units??
And which is the purpose of this??

It just means that your units of distance and time are such that c=1 in that system of units. E.g. if you measure time in years and distance in lightyears.Casco said:What is the meaning of a frame of reference where $c=1$ ?
Natural units always have c=1, but not all systems where c=1 are natural units.Casco said:Are these the so called natural units??
It makes calculations easier.Casco said:And which is the purpose of this??

There is no purpose other than making calculations easier:Casco said:Can you tell me which is the system of natural units?? Because I have seen G=c=h=1, Is it that??
And, its purpose is just making calculations easier or is it there something else besides that?
DaleSpam said:This question is fine

Natural units are a system of measurement where fundamental physical constants, such as the speed of light, are set to a value of 1. This simplifies equations and removes the need for conversion factors.
The speed of light, denoted as c, is a fundamental constant in physics that has the same value in all inertial reference frames. By setting it to 1 in natural units, it becomes a unitless quantity and simplifies mathematical equations.
In natural units, other physical quantities are expressed in terms of combinations of the fundamental constants. For example, length is expressed in units of time, mass is expressed in units of energy, and electric charge is expressed in units of length times mass divided by time.
Using natural units can simplify equations and make them more elegant. It also removes the need for conversion factors and can make calculations more intuitive. Additionally, natural units can reveal underlying symmetries and relationships between different physical quantities.
Yes, natural units are commonly used in theoretical physics, particularly in the fields of quantum mechanics and general relativity. They are also used in high energy physics and cosmology. However, in experimental physics, measurements are typically still expressed in traditional units.
