"Meter" is the root word of decimeter, because "deci" is a prefix. It is used in metric prefixes.
The basic prefixes deci, centi and milli decrease by powers of ten and deca, hecto and kilo increase by powers of ten.
The abbreviation for the prefix Hecto is "h-" for the metric system.
A metric prefix or SI prefix is a unit prefix that precedes a basic unit of measure to indicate a decadic multiple or fraction of the unit. The various prefix unit are kilo , hecto,deca,deci.
In the metric system, the base units relate to the dimension being measured: kilogram for mass, meter for length, second for time, ampere for electric current, and a few others. (see related link) The liter is not an official SI unit but is commonly accepted as a unit of volume. The prefixes represent a power of ten that is multiplied to give a unit of a certain value. See the related link for a table of prefixes. Some examples are kilo- (meaning 1000) gives kilometer (1000 meters) and kilogram (1000 grams). Milli- (derived from the Latin word for 1000, but meaning 1/1000 or 0.001); therefore, milligram is 0.001 grams, millimeter is 0.001 meters, milliliter is 0.001 liters, and millisecond is 0.001 seconds. Any of the prefixes can be used with a unit, but some are more commonly used than others. Prefixes can also be used with derived units which have special names. For example: kilowatt, kilopascal.
1000
1000 kilograms = 1 tonne. For larger amounts, either kilograms or tonnes are usually used - it is not common to use the usual metric prefixes "Mega", "Giga"
The prefix for 10-9 is nano-.
Every prefix in the metric system denotes a power of 10.
Power is usually measured in watts, which is equal to joules/second. Metric prefixes may be used, such as (for larger amounts of power) kilowatts or megawatts.
centum - hundred centimeter
Metric time is the measure of time interval using the metric system, which defines the second as the base unit of time, and multiple and submultiple units formed with metric prefixes, such as kiloseconds and milliseconds.
mili, deci, centi, hecto, kilo, deka
'King Henry Died By Drinking Chocolate Milk' (or 'King Henry Died While Drinking Chocolate Milk') is a mnemonic to remember the metric system prefixes in order (largest to smallest). The phrase stands for kilo-, hecto-, deka-, base/unit (no prefix), deci-, centi-, milli-.

All distances are measured in metres. Prefixes are used to indicate multiples or fractions of a metre.
