Design across scales

The Modified Mercalli intensity scale measures the effects of an earthquake at a given location.
This is in contrast with the seismic magnitude usually reported for an earthquake.

Multi-scale camouflage is a type of military camouflage combining patterns at two or more scales, often with a digital camouflage pattern created with computer assistance.
The function is to provide camouflage over a range of distances, or equivalently over a range of scales, in the manner of fractals, so some approaches are called fractal camouflage.
Not all multiscale patterns are composed of rectangular pixels, even if they were designed using a computer.
Further, not all pixellated patterns work at different scales, so being pixellated or digital does not of itself guarantee improved performance.

Scaling is the ratio of an organ pipe's diameter to its length.
The scaling of a pipe is a major influence on its timbre.
Reed pipes are scaled according to different formulas than for flue pipes.
In general, the larger the diameter of a given pipe at a given pitch, the fuller and more fundamental the sound becomes.

Rail transport modelling uses a variety of scales to ensure scale models look correct when placed next to each other.
Model railway scales are standardized worldwide by many organizations and hobbyist groups.
Some of the scales are recognized globally, while others are less widespread and, in many cases, virtually unknown outside their circle of origin.
Scales may be expressed as a numeric ratio or as letters defined in rail transport modelling standards The majority of commercial model railway equipment manufacturers base their offerings on Normen Europäischer Modellbahnen (NEM) or National Model Railroad Association (NMRA) standards in most popular scales.

The Richter scale, also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the magnitude scale.
This was later revised and renamed the local magnitude scale, denoted as ML or ML .

Scale of temperature is a methodology of calibrating the physical quantity temperature in metrology.
Empirical scales measure temperature in relation to convenient and stable parameters or reference points, such as the freezing and boiling point of water.
Absolute temperature is based on thermodynamic principles: using the lowest possible temperature as the zero point, and selecting a convenient incremental unit.
