Scientific Specific Units

[Dirk.]

Is this really the right place to discuss HP's update policy?

However, it might be the right place to think about the units-problem.
MeV is often used in the context of nuclear and particle physics. Usually a system of natural units is used, where c=1 (without any unit). So E=mc² becomes E=m (or E² - p² = m² instead of E²-p²c²=m²c^4). This means giving up the feasibility of dimensional analysis.

Should a calculator support this? I personally don't think so. This will create a lot of confusion among not so experienced users, whereas physicists should be able to convert and do the calculations correctly.

-> Therefore: Keep the system as it is - consistent.

But this is only my personal opinion. The people making their living from producing the calculator have to decide.
