The metric system is an improvement over the English system in three major points: One unit of measurement for each physical quantity. No matter from which other quantities of the SI system derived, yields always the same unit. Scalability by prefixes- combinations of prefix and unit make for a plethora of convenient combined units.

What is the unit of mass in the metric system?
Weight. To measure weight in the metric system, we use the gram. The gram is the unit for mass in the metric system, but we tend to use it to refer to weight. When you weigh yourself, you will see that your scale gives you the option of using pounds or kilograms.
What is the metric unit of time?
The metric unit for time is the one that is used all over the world. This is the unit that is used in stopwatches. We can say that a sprinter finished in 4.3 seconds. The metric system defines the second. We know the second as being 1/60 of a minute, and there are 60 seconds in a minute. The minute, however, is not defined in the metric system. We are just used to using it along with the second. In the metric system, however, we have 1,000 milliseconds in one second and 1,000 seconds in one kilosecond, just like other metric units. 1 kilosecond is approximately 16.7 minutes.

What is the metric system?
The metric system is a decimal-based system of measurement. The system has units of measure for each quantity. The names of most units of measure in the metric system have two parts. One part is the unit name and the other part is the prefix. For example, in the name "centimetre", the word "centi" is the prefix and the word "metre" is the unit name.
Where is the metric system used?

Other people say that metrication can only work if all fifty states metricate at the same time. This will not happen unless the Federal Government takes the lead.
Why did French scientists decide to use the metric system?
During the French Revolution, French scientists decided that it would be better to have a new system of weights and measures. The system would be the same in all French provinces and cities. They also decided that it would be easier if the new system used 10's instead of 12's, 16's or 20's, because people normally count in 10's. The new system became the official system of measurement in France in 1799. One of the French leaders, the Marquis de Condorcet declared that " [the metric system] is for all people for all time".
Why do we use prefixes in metric system?
If the numbers are too big or too small, the metric system uses prefixes to make it easier to understand the numbers.
What are the units of measure?
The metric system was first developed in France during the French Revolution. A French law passed in 1795 defined five units of measure. Three of these names are still in use today. They are the metre which is the unit of length, the gram which is the unit of mass and the litre which is the unit of volume. Since then many other units of measure have been developed and many definitions changed. The metric system now has units of measurement for energy, power, force, electric current, radioactivity and many others. The most commonly used units of measure in the metric system are listed below.
