For the basic prefices you could try the mnemonic:
King Henry Died By Drinking Chocolate Milk
for Kilo, Hecto, Deka, Base, Deci, Centi, Milli.
Base stands for metre, gram, litre etc, the basic unit.
There are other variations.
This only goes from 103 to 10-3 in multiples of 1/10. There are others that go from Yotta (1024) to the Base in steps of 10-3, and from the base to Yocto (10-24) but these are rather more difficult to remember, partly because of the letters involved and partly because the same letters occur in both sequences - much in the same way that deka and deci do above.

Than all people will have to use metric measurement. Schools will have to provide special courses for teaching metrics, metric tools for measuring will have to be bought, and everything will have to be relabeled. * * * * * But if all people use the metric system then you will have standard measurements! The question is about what will happen if you don't.
Please take a look at the Wikipedia article "SI prefixes". There you can see the values of prefixes such as "mega", "kilo", and others. The prefixes are the same for all units. For example, "micro" always means a millionth, whether it is applied to gram, to hertz, to seconds, etc.
The metric system uses conversion factors of 10 for all units. Instead of remembering all the different conversions between each unit (4quarts=1gallon, 5280feet=1mile, ect), you only have to memorize a couple of prefixes. The (common) metric prefixes are Milli=1000th Centi=100th Deci=10th Deka=x10 Hecto=x100 Kilo=x1000
All distances are measured in metres. Prefixes are used to indicate multiples or fractions of a metre.
You don't, miles are not a unit in the metric system. All distances are measured in metres. Prefixes are used for multiples or fractions of a metre. Distances that used to be measured in miles would, today, be measured in kilometres.
u kill them and then u wont have anything to memorize
The base unit of mass is the kilogram, all masses are measured in kilograms All other prefixes are fractions or multiples of kilograms, but they are still kilograms.
All Muslims memorize Quran, partly or fully. See related question for more information.
Their are no prefixes for selfish
Practice playing them. Memorize the pattern steps.
Volumes are measured in cubic metres. Because the unit is cubed the normal system of prefixes can become confusing, so it is common to use the older, non SI, unit litre. a cubic metre is 1000 litres. The normal prefixes apply to litres.
memorize a dictionary
There is none but sometimes you may find "myriad".The SI system discourages all prefixes that are not thousand multipliers or dividers. However certain prefixes are so historically entrenched that they will not vanish soon. Some examples of 'unsupported' prefixes are: centimeter (hundredth) decimeter (tenth) decathelon (ten) hectoliter (hundred)
The metric system isn't used for day to day time measurement. The point of the metric, or SI, system is that it is a universal standard, the normal 24 hour clock is already the established universal system. Within the SI system the base unit of time is the second, all the normal prefixes apply, but since multiples of seconds are generally quoted in minutes and hours, the prefixes are mainly used with fractions of a second; milliseconds, nanoseconds etc.
