To convert from one unit to another within the metric system usually means
moving a decimal point
. If you can remember what the prefixes mean, you can convert within the metric system relatively easily by simply multiplying or dividing the number by the value of the prefix.
What are the disadvantages of using the metric system?
The only major disadvantage in using the metric system is
that it’s not well-suited for working with fractions
. For example, 1/6 meter is approximately equivalent to 167 millimeters and 1/3 kilogram is approximately equal to 333 grams.
Why it is easy to change from one unit to another in the metric system?

What is the importance of converting one unit to another?
Units can:
Help to show another person the exact amount you have
.
Assist in solving a mathematical problem
, especially in chemistry, where you can follow the units to get to the answer. Show which measurement system the person is using (i.e. metric or standard)
What allows you to switch from one system of units to another?
A conversion factor
is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot.
Why we shouldn’t use the metric system?
Expensive. The expense of the U.S. changing over to the metric system translates into changed measurements on
all packaged products
, starting with food. The change would also impact housing and lot sizes, the measurement of temperatures with the new use of Celsius, and the change of mileage and speed signs.

simply time and money
. When the Industrial Revolution began in the country, expensive manufacturing plants became a main source of American jobs and consumer products.
What are 3 benefits of using the metric system?

Is a conversion factor equal to 1?
A conversion factors is
a fraction that equals one
. Multiplying a quantity by a conversion factor changes the units that measure a quantity but does not change the original amount of the quantity. Conversion factors equal unity (1) because they are made from equalities.
What is the importance of unit?
For most quantities a unit is
necessary to communicate values of that physical quantity
. For example, conveying to someone a particular length without using some sort of unit is impossible, because a length cannot be described without a reference used to make sense of the value given.
Will US ever go metric?
The United States has official legislation for metrication
; however, conversion was not mandatory and many industries chose not to convert, and unlike other countries, there is no governmental or major social desire to implement further metrication.
Does NASA use the metric system?
Although
NASA has ostensibly used the metric system since about 1990
, English units linger on in much of the U.S. aerospace industry. In practice, this has meant that many missions continue to use English units, and some missions end up using both English and metric units.
Why do Americans use Fahrenheit?
Fahrenheit is a
scale used to measure temperature based on the freezing and boiling points of water
. Water freezes at 32 degrees and boils at 212 degrees Fahrenheit. This is used as a metric for determining hotness and coldness.
Why does America still use imperial?
Why the US uses the imperial system.
Because of the British
, of course. When the British Empire colonized North America hundreds of years ago, it brought with it the British Imperial System, which was itself a tangled mess of sub-standardized medieval weights and measurements.
