Top Definition

1. Size; extent; dimensions: to determine the magnitude of an angle.

2. Great importance or consequence: affairs of magnitude.

3. Greatness of size or amount.

4. Moral greatness: magnitude of mind.

5. Astronomy.

In mathematics:

- Magnitude (mathematics), the relative size of a mathematical object.

- Magnitude (vector), a term for the size or length of a vector.

- Scalar (mathematics), a quantity defined only by its magnitude.

- Euclidean vector, a quantity defined by both its magnitude and its direction.

- Order of magnitude, the class of scale having a fixed value ratio to the preceding class.

In astronomy:

- Magnitude (astronomy), a measure of brightness and brightness differences used in astronomy.

- Apparent magnitude, the apparent brightness of a celestial object as observed from Earth.

- Absolute magnitude, the brightness of a celestial object corrected to a standard luminosity distance.

- Photographic magnitude, the brightness of a celestial object corrected for photographic sensitivity, symbol mpg

- Magnitude of eclipse or geometric magnitude, the size of the eclipsed part of the Sun during a solar eclipse or the Moon during a lunar eclipse.

As an earthquake unit of measure:

- Richter magnitude scale,a measure of the energy of an earthquake.

- Moment magnitude scale, an alternative to the Richter scale for measuring earthquakes.

- Hence, ' things by removal ' may be one way of explaining perceptible magnitudes qua lengths.

- You cannot visit the Eden Project without being amazed at the sheer magnitude of it all.

- There is a great increase in the number and magnitude of earthquakes, many centered in the localities of the wars and fighting.
