Because if everyone used different systems of measurement there would be no way for results to be accurately compared. 10ml is 10ml everywhere on the Earth but if I decided to measure things in squirlybobs and you measured them in noodfings how would we compare them with the degrells measured by yet another person?
A real world example: A NASA probe scheduled to land on Mars for scientific research crashed because a contractor used traditional English measurements while NASA works with the metric system (the scientific standard). That embarrassing mistake cost NASA 125 million dollars, and it shows why a standard universal system of measurement in science is crucial for collaboration on which so much of science is based.
Because standardising units of measurement - means that, no matter which country you're in - the measurement will always mean the same quantity or distance.
One of the fundamental requirements of science is the ability for other researchers to reproduce results. That would not be possible if the measurements were not standardised. Also, if they did not, then it increases the chances of a disaster like the one that trashed NASA's Mars Climate Orbiter - possibly the most expensive piece of junk metal!
So other scientists can replicate the experiment and obtain identical results, or apply the data to their own research. Neither can happen without a standardized measurement system.
It isn't - it's just convenient.
Apparently it's not as universal as you think.
Universal indicator is just that - an indicator. It is not intended as an accurate measurement system.
The Metric system ex: centermeters, milliliters , and grams
Established in 1960 by the international agreement, the "Metric System" is the international standard of measurement.
The French National Assembly commissioned the Academy of Science to create the decimal based system of measurement in 1790.
Almost all real science involves measurements. A universal system of measurement is necessary, or at least very very convenient, in science, in order to make it possible for different scientists to tell each other about their work ... what they did and what the results were ... and even for different scientists in different places to work together on the same thing. The universal system that's used in today's world is the "SI" system, or the "metric" system. Look it up and read about it, either on line or in a real book, to learn about its units. Here are three of them to get you started: -- the Meter -- the Kilogram -- the Second
The metric system
A system of measurement is a set of units of measurement which can be used to specify anything which can be measured and were historically important, regulated and defined.Two major system of measurements in science are S.I baseunits and S.I derived units.
Given that only Liberia and Burma officially share the US measurement system, it can hardly be described as universal!
Apparently it's not as universal as you think.
IUPAC unit
Not universal
Metric System since its the easiest system to convert from.
so that bums(u) can get jobs there
a system of measurement for science, industry and commerce
Si unit
Universal indicator is just that - an indicator. It is not intended as an accurate measurement system.
