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.
Yes, it is recommended because the SI-units are based on the metric system.
Almost all scientists use metric units for scientific measurements.
Units of length, such as mm, are used for this.
Because the metric system uses units of 10's to measure which makes things simple.
Basically all the basic and derived SI units. More information here: http://en.wikipedia.org/wiki/SI_units#Units
to standardize all units of measurement
Metric units originated from France. During the 1790s, the National Assembly of France requested that the French academy of Science create a new system, one that was accurate and standard to be used.
It is a more logical system, where everything is divisible by 10. With other units, everything is arbitrary.
The Metric system ex: centermeters, milliliters , and grams
Metric units include millimeters, centimeters, decimeters, and meters.
Yes, the metric system is now officially known as the International System of Units
The metric system is a system of measurement based on the meter, kilogram, and second as fundamental units. It is used in science and measurement to provide a standardized and consistent way to quantify and compare physical quantities. Scientists use the metric system because it is easy to convert between units and promotes international collaboration and communication.
