The only SI unit that's used by everyone in the US is the unit of time ... the 'second'.
All of the other SI units are used in the US, but only by people who make things that
they want to be able to sell to other countries, and by people who want to be able to
shop in other countries and understand the products they see, and by people who
are involved in scientific or technological activities and want to be able to understand
what other scientists and engineers are doing.

What is 1 1000 of a gram?
A miligram. Grams are an SI unit, so they go with all the standard SI prefixes.
What is the unit of a mass that is equal to one one thousandth of a gram?
A "milligram". In general, the prefix "milli-" means 1/1000, no matter what unit it is used with; I recommend that you check the Wikipedia article on "SI prefixes", for additional prefixes of this kind.
How do you measure temperature in the SI measuring system?
The SI unit of measurement for temperature is the kelvin(K). Celsius is not an SI unit (it is a metric unit), but may be used alongside it.
What is the fundamental unit of mass in the metric system?
The fundamental unit is the gram. However the standard unit (SI) used is the kilogram (1000 grams).AnswerThe terms 'fundamental unit' or 'standard unit' are not used in SI. The correct term is 'base unit', and the base unit for mass is the kilogram.
Explain why prefixes are useful with SI units?
Sometimes you need a very large, or a very small, amount of a certain unit. One way to deal with that is to use prefixes like kilo, mega, milli, micro, and others.
Is feet an SI unit?
No. The SI unit of length is the meter; the same unit with prefixes (such as millimeter and kilometer) is also used.
What unit of force is smaller than the newton?
In the SI, the usual SI prefixes would be used for smaller units - prefixes such as milli, micro, etc.
What is the practical si unit of force?
In the SI, force is measured in newtons. For very large or very small forces, it is of course possible to use the standard SI prefixes, but quite often, the unit used is simply the Newton, without any prefixes.
The SI unit for mass is the what?
The SI unit of mass is the kilogram. However the prefixes are based on the gram.
What unit is volume usually measured in?
milliliters, deciliters, litersAnswer:The official SI unit for volume is the cubic meter. Surprisingly, the liter is not the official SI unit of volume, although is is commonly accepted as such and used with metric prefixes.

What the SI unit for temperatures?
The scale used is usually Celsius or Kelvin.AnswerThe SI unit of temperature is the kelvin (K). Celsius is a metric unit, but not an SI unit, although it may be 'used alongside' the SI system.
What SI unit used to measure mass?
The official SI unit for mass is the kilogram.
Need of SI unit?
SI units are used fundamentally.SI unit is used by everyone. Hence, it is a standard unit for measurement.
