For most physical measurements, zero is the same regardless of the units used for the measure: $0 \mathrm$ Are there any other physical, measurable quantities (other than temperature) that have different zero points? I'm looking for measurable quantities that are applicable anywhere -- things like voltage or temperature, not local quantities like "distance from the Empire State Building". $\begingroup$ It seems like what makes temperature unique is not that it has a zero point but that the zero point (absolute zero) is meaningful. Pretty much any quantity could have absolute and relative versions (date-time versus time interval, position versus displacement) but the zero is usually arbitrary, without universal physical meaning. A lot of the answers are like this right now, so it's not terribly interesting. $\endgroup$ $\begingroup$ I don't think this answers the question. Temperature is scale in which changing the scale forces you to change the zero point. The zero point and the unit of time are independent; if I was measuring time in seconds and I want to change it to minutes, I don't shift $t=0$, I just divide everything by $60$. $\endgroup$ $\begingroup$ Excellent answer, and I think a very close analogy to temperature scales. The Gregorian (AD/BC) attempts to put year 0 at the birth of Christ (sort of), the Hebrew calendar puts year 0 at the creation of the world, the Roman calendar put year 0 at the founding of Rome, the Julian period puts day 0 at the confluence of s...

Instrument zero inspection and adjustment is a skill that instrument operator must master. This article introduces the method of checking and adjusting zero point of pressure transmitter, differential pressure transmitter, thermocouple display instrument and thermal resistance display instrument, It is of great help to the instrument operators for improving their technical level. When the operator has doubts about the indicator value of the instrument, it is necessary to check the instrument, the most commonly used method is to check whether the zero point of the instrument is correct. For pressure transmitter and differential pressure transmitter, check zero point after stopping process. The zero point of the instrument refers to the lower limit of the instrument's measuring range (that is, the minimum value that the instrument can measure under its specific precision). The purpose of adjustment is to make the upper limit of the transmitter’s output signal correspond to the upper limit of the measurement range, Equivalent to changing the slope of the output characteristic of the transmitter. The purpose of zero adjustment and zero migration is to make the lower limit of the transmitter output correspond to the lower limit of the measuring range. Zero adjustment makes the starting point of transmitter’s measurement be zero, Zero-point migration is to transfer the starting point of measurement to a certain value(Positive value or negative value). Zero point transferring and...

$\begingroup$ You can always add or subtract a constant from the Hamiltonian without altering the physics. The standard statistical mechanics formula typically assume that the ground state of the system has zero energy, i.e. the zero of energy is set such that there is no zero point energy. A system is at absolute zero if and only if it is certain to be in its lowest energy state (whatever the energy of that state may be) $\endgroup$ Thanks for contributing an answer to Physics Stack Exchange! • Please be sure to answer the question.
