   • And on a programme of works of this magnitude, passengers will need to be mindful of the age-old maxim of 'no gain without pain'. 2020 September 23, Paul Stephen, “East Coast upgrade: changes to schedule... but on schedule”, in Rail, page 31:
2. (countable) An order of magnitude.
3. (countable, uncountable) A number, assigned to something, such that it may be compared to others numerically
4. (countable, uncountable) Of a vector, the norm, most commonly, the two-norm.
5. (uncountable) A logarithmic scale of brightness defined so that a difference of 5 magnitudes is a factor of 100. ▸ The apparent brightness of a star, with lower magnitudes being brighter; apparent magnitude
6. (countable) A logarithmic scale of brightness defined so that a difference of 5 magnitudes is a factor of 100. ▸ A ratio of intensity expressed as a logarithm.
   • Observations in the infrared domain allow one to penetrate the ~25-30 magnitudes of extinction present at visible wavelengths. 2005, Andreas Eckart et al., The Black Hole at the Center of the Milky Way, →ISBN, page 71:
