# magnitude

Earthquakes have great magnitude in that they are powerful. Their power is rated by their level of magnitude, or how much energy they release relative to other earthquakes.

In math, magnitude compares numbers by powers of 10. If your weekly allowance was \$10, but your brother's was \$100, his allowance would be one order of magnitude higher than yours. If your sister's was \$10,000, hers would be three orders of magnitude higher. A difference of that magnitude is just not fair!

### n relative importance

“a problem of the first magnitude
Types:
extensiveness, largeness
large or extensive in breadth or importance or comprehensiveness
Type of:
importance
the quality of being important and worthy of note

### n a number assigned to the ratio of two quantities; two quantities are of the same order of magnitude if one is less than 10 times as large as the other; the number of magnitudes that the quantities differ is specified to within a power of 10

Synonyms:
order of magnitude
Type of:
ratio
the relative magnitudes of two quantities (usually expressed as a quotient)
