If you got at least half of those, you are doing a great job! With a bit more practice and you will be converting SI units with ease. Using these two pieces of information, we can set up a dimensional analysis conversion.ĩ55\text Kilogram refers to 10 3 grams, while megagram refers to 10 6 grams. We will need two pieces of information from the table above. Let’s try converting 955 kilograms to megagrams. Here is an example of a one-step conversion between the SI system prefixes.
Of course, you can always refer back to the tables above. Memorizing the different prefixes and their meanings makes it a lot easier to do these conversions, so try to memorize as many as you can. Interested in an Albert school license? Converting SI UnitsĬonverting between the different SI system prefixes is an essential science skill that requires practice. For example, speed can be measured in meters per second, or in kilometers per nanosecond. The different base units can also be combined to form what are called derived units. Instead, you would use kilometers or even megameters. Applying a unit conversion to LOINC 163626 converts its test results from micromoles per liter to micrograms per deciliter. For example, you wouldn’t measure the distance from LA to New York in meters, the base unit. shows the distribution of laboratory results for 2 ammonia LOINC codes measured in either micrograms per deciliter (LOINC 227637) or micromoles per liter (LOINC 163626).
These base SI units can be combined with any of the prefixes to create units that are most appropriate for what is being measured. A circular slide rule used to compute dew point and relative. These reference tables show the different bases and prefixes used to designate metric units with the SI system. SI units are included with the conventional US.
