You perform the calculation: 35920 / 172 on your calculator and its output is. for the number 436 the decimal point is to the right of the 6, as such: 436. Which pair correctly matches the prefix symbol with its multiplier.

A number with no decimal point shown has an implicit decimal point to the immediate right of the farthest right digit (i.e.Follow the metric prefix number line to know which direction you skip the decimal point for conversion purposes., or 23 microamps (♚)Įxample problem: express 304,212 volts in terms of kilovolts.ģ04,212 volts (has no prefix, just plain unit of volts)įrom the (none) place to kilo place on the number line is 3 places (powers of ten) to the left, so we need to skip the decimal point 3 places to the left:Įxample problem: express 50.3 Mega-ohms in terms of milli-ohms.įrom mega to milli is 9 places (powers of ten) to the right (from 10 to the 6th power to 10 to the -3rd power), so we need to skip the decimal point 9 places to the right:ĥ0.3 M ohms = 50,300,000,000 milli-ohms (mΩ) Prefixes are commonly used in expressing a unit of measurement. This layout was purposely chosen to make it easier to remember which direction you need to skip the decimal point for any given conversion.Įxample problem: express 0.000023 amps in terms of microamps.Ġ.000023 amps (has no prefix, just plain unit of amps)įrom UNITS to micro on the number line is 6 places (powers of ten) to the right, so we need to skip the decimal point 6 places to the right:Ġ.000023 amps = 23. now on your calculator to see which form it uses to display scientific notation. Notice that the metric prefix “number line” in the previous section was laid out from larger to smaller, left to right.

Mathematics - Mathematical rules and laws - numbers, areas, volumes, exponents, trigonometric functions and more. To express a quantity in a different metric prefix from how it was originally given, all we need to do is skip the decimal point to the right or to the left as needed. Basics - The SI-system, unit converters, physical constants, drawing scales and more.
