When applying prefixes to derived units of area and volume that are expressed in terms of units of length squared or cubed, the square and cube operators are applied to the unit of length including the prefix, as illustrated here:

When not qualified, the term " luminosity " means bolometric luminosity, which is measured either in the SI units, watts, or in terms of solar luminosities.

When speaking of political ecology and conservation, one ultimately finds that there is a divergence of ideas, issues, and troubles, especially when looking at conservation through biodiversity and the creation of conservation units.

When the activation energy is given in molecular units instead of molar units, e. g., joules per molecule instead of joules per mole, the Boltzmann constant is used instead of the gas constant.

When the metric system was introduced in France in 1795, it included units for length, area, dry volume, liquid capacity, weight or mass, and even currency, but not for time.

When using degree as the units, the arc's length is compared to 1 / 360 of the circumference of the circle.

When silicon technology allowed for wider implementations ( with more execution units ) to be built, the compiled programs for the earlier generation would not run on the wider implementations, as the encoding of the binary instructions depended on the number of execution units of the machine.

When lamb and mutton are irradiated at substerilization doses, the meat becomes dehydrated, the fat becomes chalky, and, again, unnatural changes in color occur.

When used appropriately, opioids and similar narcotic analgesics are otherwise safe and effective, however risks such as addiction and the body becoming used to the drug ( tolerance ) can occur.

When subjected to loading, debonding may occur at different locations in the adhesive joint.

When an APAF-1 gene trap is introduced into cells, many morphological changes occur, such as spina bifida, the persistence of interdigital webs, and open brain.

When assured by Mersenne that it was, indeed, the product of the son not the father, Descartes dismissed it with a sniff: " I do not find it strange that he has offered demonstrations about conics more appropriate than those of the ancients ," adding, " but other matters related to this subject can be proposed that would scarcely occur to a sixteen-year-old child.

When barter did in fact occur, it was usually between either complete strangers or would-be enemies.

When context switches occur frequently enough the illusion of parallelism is achieved.

When the process of escape and return reaches an equilibrium, the vapor is said to be " saturated ," and no further change in either vapor pressure and density or liquid temperature will occur.

When the bid matches the offer, a transaction can easily occur ( even instantenously, as in a typical stock market ).

* When certain consonants occur together, special conjunct symbols are used which combine the essential parts of each letter.

When President Aristide returned to Haiti, some improvements did occur in the manufacturing sector.

When making assessments of how often relatively rare events will occur, analyses are made in terms of the return period of such events.

When inspired air contains CO levels as low as 0. 02 %, headache and nausea occur ; if the CO concentration is increased to 0. 1 %, unconsciousness will follow.

# When a given style of production relations no longer supports further progress in the productive forces, either further progress is strangled, or ' revolution ' must occur.

When this approach is used, the hash function must be chosen so that the result has fairly uniform distribution between 0 and n − 1, for any value of n that may occur in the application.

When the Sun is active, strong solar flares can occur that will hit the sunlit side of Earth with hard X-rays.

When either writing through or directly to physical device registers, this may, but not necessarily, cause a real interrupt to occur at the device's central processor unit ( CPU ), if it has one.

When a hydrated crystal is left in air, dehydration may occur slowly.

When transaction costs are low and parties involved are perfectly informed, a mutually beneficial agreement will occur: whoever values the property the highest will end up with it.

When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow may occur depending on the velocity of the fluid: laminar flow or turbulent flow.
