magnitude 【magnitude】n.大小；量；长（度）A crowd of great magnitude attended the President's inauguration.大批民众参加总统就职典礼。

Accepted Answer

['mæɡnɪtuːd] 
magnitudethe property of relative size or extent (whether large or small)
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!
