Because everything must all be in the same unit system, e.g. Imperial, or metric (SI). You can't do any arithmetic like adding or multiplying on two numbers in different unit systems. For example, you can't add 100 km to 100 mi. The answer wouldn't make any sense. First you must convert one to the other, either miles to km or km to miles and so the result to would from 100 mi + 60 mi (approx. 100 km) = 160 mi.

what measurements did they use in ww2
importance- Puritans wanted their ideals to be passed down from generation to generation. weakness- As society evolved, the next generations didn't want to have to pubically announce their sins and be constantly watched in the close knit Puritan societies. Thus, people weren't being baptized so the Halfway Covenant system came about.
measurements
Tycho Brahe (and his assistants) recorded measurements at his observatory on the island of Ven with an accuracy of up to 4 seconds of arc. Most of his measurements were angular measurements between celestial objects (between stars, between planets and stars and between planets).
A rate that compares two equivalent measurements is a conversion rate.
to help people
The measurements must be equal to each other.
It's usually just called conversion, or unit conversion.
The conversion factor for the keyword "au" unit in astronomical measurements is 1 astronomical unit (au) is equal to approximately 149.6 million kilometers.
Could be the conversion factor - but only if the two sets of measurements are on scales that are linear AND absolute.
conversion factor
It is the conversion factor between the measurement units.
By unit of length and mass and conversion ,we can say that units of measurements in length are meters ,cm ,dm ,dam ,hm.
Calculator industies 8025 makes a conversion calculator.
You can convert measurements using online services such as onlineconversion.com. Also, many scientific calculators have programs which convert measurements.
For two measurements to be a conversion factor, they must represent the same quantity but in different units. The ratio should equal 1 and can be written as a fraction where the units cancel out, allowing you to convert from one unit to another.
