So I was getting my nerd on when I came across afew measurements I had never heard of before.
And the measurement was one femtometre. The size roughtly of a Proton/Neutron. Then after reading some more I came across a Yoctometre. If protons and neutrons are the building blocks of everything (the smallest thing we have) what is the measurement “yoctometre” used to measure?
So if anyone can help me out that would be sweet
It is used to measure whatever you are measuring. Orders of magnitude of measurements eg picometre, nanometre etc are just a handy short handed way of saying “1 millionth of a metre” or whatever.
Some measurements are more useful in some situations, but they weren’t necessarily “made” in order to measure something.
For example a light year is a huge distance that is often used to describe the distance between stars or galaxies, but it is only used to describe these distances because it is a conveniently huge distance.[/quote]
I understand what you are saying. For example I work in construction and we always use millimetres(mm), well 99% of the time. So I guess when one is talking quantum physics thats when they would use it.
