To enable the indication of sizes which differ greatly without the need to write a long string of digits and text.
For example, it would be stupid to measure the diameter of a bacteria in kilometres or the force of a nuclear blast in milligrams.

A thermometer and light meter are the most useful when measuring two environmental changes.
A spectrophotometer is typically the most useful equipment for measuring wavelength. It can measure the absorbance or transmittance of a substance at different wavelengths, allowing for the determination of the wavelength of maximum absorbance or transmittance.
Sonar is useful because it allows for the detection and location of objects underwater by sending out sound waves and measuring their return time. This technology is widely used in various applications such as navigation, fishing, oceanography, and military operations where visibility is limited. Sonar provides valuable information about underwater environments and helps in conducting efficient and safe operations.
One newton (N) is equal to the amount of force needed to move 1 kilogram of substance one centimeter per second. This unit of measure can be useful when measuring the amount of force medium to large sized objects experience.
For example a thermometer.
The wavelike properties of electrons are useful in explaining various physical phenomena, such as interference and diffraction patterns observed in electron microscopy and electron diffraction experiments. These properties also play a role in understanding the behavior of electrons in materials, such as in the band theory of solids. Additionally, the wave nature of electrons is essential in describing their behavior in quantum mechanics.
You could measure lengths of small objects like a pen or bookshelf in decimeters. Decimeters are one-tenth of a meter, so they are useful for measuring lengths that are between centimeters and meters.
