measurement which can only be determined by applying theories or principles in conjunction with any customary measuring device(s), such as a ruler, scale, meter (see also derived measurement)

A process where the measurement of some entity is not obtained by the direct reading of a measuring tool, or by counting of units superimposed alongside or on that entity. For example if the length and width of a rectangle are multiplied to find the area of that rectangle, then the area is an indirect measurement.

a measurement of some other temperature from which one can infer the product temperature

A measurement which is found by using a formula or other strategy and not actually measuring something (e.g., finding the height of a tree without actually holding a ruler next to it).

a measurement determined without the direct application of measurement tools.  For example finding a measure by the use of the Pythagorean theorem, by similarity, or through ratios or scale factors.

A way to measure a solid, liquid or gas using the measurement device, the substance being measured, and another substance or container. See “displacement of water

Methods for determining heights, distances, and other quantities that cannot be measured directly.
