# measurement (quantitative)

A process that uses a regular pattern applied to a thing's space or size, where the difference is recorded as a numerical quantity.

## Emergence
**Emerges from:** [regularity](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-regularity.pattern), [quantity](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-quantity.numerical), [space](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-space.extent), [size](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-size.measurement), [application](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-application.use), [difference](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-difference.relation), [process](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-process.general), [property](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-property.attribute), [applying](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-applying.action), [pattern](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-pattern.regularity), [recorded](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-recorded.information), [records](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-records.document), [regular](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-regular.frequency), [use](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-use.application)

**Through:** A regular pattern is applied to spatial or size extent, and through comparison, a difference emerges that is captured as a numerical property.

**Novel properties:**
- quantified magnitude
- measured distinction
- recorded numerical difference

## Examples
- The International Prototype of the Kilogram in Paris defined mass for 130 years until the 2019 redefinition. *(physics)*
- NASA's Voyager 1 spacecraft transmitted telemetry showing 2.7 K cosmic background radiation across interstellar space. *(spaceflight)*
- The 1989–2001 Large Hadron Collider construction required micron-level alignment of 1232 dipole magnets. *(engineering)*
