SUMMARY

The symbol [=], as discussed in the context of dimensional analysis, is not widely recognized or used in scientific literature. Participants in the forum clarified that while the notation could imply a relationship between a quantity and its units, such as [t] = seconds, the specific notation [=] lacks established usage. Examples provided include the notation for momentum, [p] = MLT-1, which is accepted in dimensional analysis. Overall, the consensus is that [=], particularly in the form presented, is not standard.

What does the symbol [=] mean?

Homework Equations



The Attempt at a Solution



I tried looking this up online but can't find anything. I think it has something to do with dimensional analysis or denoting the units of a quantity. E.g., is it valid to write:

t [=] seconds

?
 
Physics news on Phys.org
Could you provide some context or a few examples?
As long as the brackets are meant to belong to the sign, I have never seen this before. It might well be, that it denotes a dimension, as it would be in, e.g. ##[\vec{p}] = MLT^{-1}## (mass length / time) for momentum. A notation I've seen before. But I don't think it is in general use. And I can't see how ##t[=] \text{ seconds }## would make sense. Eventually ##[t] = \text{ seconds }##.
 
Google can't find [=] anywhere so very unlikely it exists.
