magnitude

Definition of Magnitude in English :

Noun

1. magnitude

the property of relative size or extent (whether large or small)

Example Sentences:
'they tried to predict the magnitude of the explosion'
'about the magnitude of a small pea'

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

order of magnitude

3. magnitude

relative importance

Example Sentences:
'a problem of the first magnitude'

noun

1.

relative importance or significance

a problem of the first magnitude

2.

relative size or extent

the magnitude of the explosion

3. mathematics

a number assigned to a quantity, such as weight, and used as a basis of comparison for the measurement of similar quantities

4. Also called: apparent magnitude astronomy

the apparent brightness of a celestial body expressed on a numerical scale on which bright stars have a low value. Values are measured by eye (visual magnitude) or more accurately by photometric or photographic methods, and range from –26.7 (the sun), through 1.5 (Sirius), down to about +30. Each integral value represents a brightness 2.512 times greater than the next highest integral value

See also absolute magnitude, visual magnitude

5. Also called: earthquake magnitude geology

a measure of the size of an earthquake based on the quantity of energy released: specified on the Richter scale

a.

of size

b.

of extent

c.

of importance or influence

d. Obsolete

of character

2.

a.

size or measurable quantity

the magnitude of a velocity

b.

loudness (of sound)

c.

importance or influence

3. Astronomy

a number representing the apparent brightness of a celestial body: it is part of an unlimited arbitrary scale that ranges from the brightest object, the sun, at -26.72 to the faintest visible object at c. 26: only 22 stars are brighter than 1.5 (first magnitude), while stars c. 6 (sixth magnitude) are barely visible to the naked eye: each increase of one magnitude equals 2.512 times as much brightness (a magnitude increase of 5 is 100 times brighter)

n.

1.

a. Greatness of rank or position: "such duties as were expected of a landowner of his magnitude" (Anthony Powell).

b. Greatness in size or extent: The magnitude of the flood was impossible to comprehend.

c. Greatness in significance or influence: was shocked by the magnitude of the crisis.

2. Astronomy

a. The brightness of a celestial body on a numerical scale for which brighter objects have smaller values. Differences in magnitude are based on a logarithmic scale that matches the response of the human eye to differences in brightness so that a decrease of one magnitude represents an increase in apparent brightness by a factor of 2.512. Also called apparent magnitude.

b. A unit on such a scale of brightness.

3. Mathematics

a. A number assigned to a quantity so that it may be compared with other quantities.

b. A property that can be described by a real number, such as the volume of a sphere or the length of a vector.

4. Geology A measure of the amount of energy released by an earthquake, as indicated on the Richter scale.
