2. order of magnitude, magnitudenoun

1. order of magnitudenoun

   The class of scale or magnitude of any amount, where each class contains values of a fixed ratio (most often 10) to the class preceding it. For example, something that is 2 orders of magnitude larger is 100 times larger, something that is 3 orders of magnitude larger is 1000 times larger, and something that is 6 orders of magnitude larger is a million times larger, because = 100, = 1000, and = a million.

1. Order of magnitude

   An order of magnitude is an approximation of the logarithm of a value relative to some contextually understood reference value, usually 10, interpreted as the base of the logarithm and the representative of values of magnitude one. Logarithmic distributions are common in nature and considering the order of magnitude of values sampled from such a distribution can be more intuitive. When the reference value is 10, the order of magnitude can be understood as the number of digits in the base-10 representation of the value. Similarly, if the reference value is one of some powers of 2, since computers store data in a binary format, the magnitude can be understood in terms of the amount of computer memory needed to store that value. Differences in order of magnitude can be measured on a base-10 logarithmic scale in “decades” (i.e., factors of ten). Examples of numbers of different magnitudes can be found at Orders of magnitude (numbers).

1. Order of magnitude

   An order of magnitude is the class of scale or magnitude of any amount, where each class contains values of a fixed ratio to the class preceding it. In its most common usage, the amount being scaled is 10 and the scale is the exponent being applied to this amount. Such differences in order of magnitude can be measured on the logarithmic scale in "decades". The order of magnitude of a physical quantity is its magnitude in powers of ten when that physical quantity is expressed in powers of ten with one digit to the left of decimal. "We say two numbers have the same order of magnitude of a number if the big one divided by the little one is less than 10. For example, 23 and 82 have the same order of magnitude, but 23 and 820 do not." - John Baez

Examples of order of magnitude in a Sentence

1. Gretchen Bergstresser:

   We expect ongoing volatility for the balance of this year, and probably continuing in 2017, based on fund flows, increases in default rates and ongoing global events whether from China or elsewhere, loans will see ups and downs, but not to the same order of magnitude at all as the high-yield bond market.

2. Gretchen Bergstresser:

   Loans will see ups and downs, but not to the same order of magnitude at all as the high-yield bond market.

3. Thomas Crowther:

   They store huge amounts of carbon, are essential for the cycling of nutrients, for water and air quality, and for countless human services, yet you ask people to estimate, within an order of magnitude, how many trees there are and they don't know where to begin. I don't know what I would have guessed, but I was certainly surprised to find that we were talking about trillions.

4. Southeastern US:

   Modeling scenarios are always approximations, but they're definitely in the right order of magnitude based on what I've seen in previous economic analysis, the most important thing from The Analysis Group study is that the economic impacts are positive, not negative. If passed, the Clean Electricity Payment Program and clean energy tax credits would be the most impactful piece climate legislation in Southeastern US history, and The Analysis Group study shows that it will not be a cost to the economy, it'll be a benefit. That's a no brainer.

5. William Taylor:

   Horse domestication was an absolute lightning strike in human history, leading to incredible, widespread, and lasting social transformations all across the ancient world, horses were an order of magnitude faster than many of the transport systems of prehistoric Eurasia, allowing people to travel, communicate, trade and raid across distances that would have previously been unthinkable.
