The units used in science include .length-meters, mass-grams, volume-liters
fro science astronomical units are used.BUt we use light year as a unit of science for distance
They are used a lot in science. However, the metric units are also used in daily life, in most countries - with the notable exception of the United States.In some cases, non-metric (non-SI) units are also used; for example, it is customary to use degrees Celsius for temperature (instead of Kelvin); or to use time units other than seconds (such as minutes, days, years) for time.
Basically all the basic and derived SI units. More information here: http://en.wikipedia.org/wiki/SI_units#Units
I need help
Use common sense.......
They're the ones we use in the U.S. like feet and inches. There are other units no longer in common usage as well. There are rods which are equal to 5.5 yards (or 16.5ft). Surveyors use some units; links and chains in addition to yards, feet and miles. There are different units for weights and volume. Many are old and have fallen out of common usage, ex. gill = 4 fluid oz.
In science, the SI unit for mass is Kilograms (Kg)
In science, volume is always measured with liters.
SI units is what we use in the United States for the common unit of measurement for matter.
The second. Also, most units that are NOT in common use, i.e., fairly unknown by people who don't work in science or technology; for example units related to electricity such as ampere, watt, henry, volt, ohm, siemens, etc.
Almost all scientists use metric units for scientific measurements.
