Expert writing Tips

Best practice

Consider that some alternatives can be less ambigous depending on what you measure.

Common error

Avoid using "by around two orders" when a more precise value is available or necessary. This phrase implies an estimation, so it's unsuitable for situations requiring exact figures.

Linguistic Context

The phrase "by around two orders" functions as a prepositional modifier, quantifying the extent of a change or difference. Ludwig examples illustrate its use in describing changes in viscosity, corrosion current density, computational cost, and thermal conductivity.

Ludwig's WRAP-UP

The phrase "by around two orders" is a prepositional phrase used to express an approximate change in magnitude, typically in scientific or technical contexts. Ludwig examples show its application in describing significant increases or decreases, such as changes in viscosity or computational cost. While considered acceptable, it's important to ensure clarity and context. Consider alternatives like "by approximately two orders of magnitude" for a more precise tone. Ludwig AI indicates that although correct, care should be taken to prevent it to sound colloquial. The register is generally neutral to formal, and the phrase is most frequently found in scientific literature and news media.

More alternative expressions

Phrases that express similar concepts, ordered by semantic similarity:

by approximately two orders of magnitude

This alternative uses "approximately" for a more precise feel instead of "around".

decreased by two orders of magnitude

This alternative focuses on a reduction instead of a general change, similar to the primary search.

increased by two orders of magnitude

Specifies an increase rather than just a general change in magnitude, similar to the primary search.

by roughly two orders of magnitude

Replaces "around" with "roughly", giving a similar level of imprecision.

by about two orders of magnitude

Substitutes "around" with "about", another common synonym for approximation.

by a factor of approximately 100

Expresses the change as a factor of 100 (two orders of magnitude) using "approximately".

by a power of approximately two

This is an alternative that focus on powers of magnitude that is useful in specific contexts.

in the range of two orders of magnitude

Focuses on defining an interval where the change lays.

increased twofold twice

While not exactly the same magnitude, increasing twice can describe the effect depending on what you measure.

increased to approximately double

Increased to approximately double can describe a similar magnitude.

FAQs

What does "by around two orders of magnitude" mean?

It means that a value has changed by a factor of roughly 100. For example, if something increases "by around two orders of magnitude", it becomes approximately 100 times larger.

When is it appropriate to use the phrase "by around two orders of magnitude"?

It's appropriate when you want to express a large, approximate change in a value, particularly in scientific or technical contexts. It suggests the change isn't precise but is substantial, around a factor of 100. Other alternatives are "by approximately two orders of magnitude" or "by roughly two orders of magnitude".

Are there more precise ways to express a similar change?

Yes, you could say "increased by a factor of 100" or "decreased by a factor of 100". However, "by around two orders of magnitude" implies an approximation, so these precise alternatives might not always be suitable.

Is "by around two orders" formal or informal?

It leans towards the informal side due to the use of "around". In more formal writing, consider using alternatives like "by approximately two orders of magnitude" or "by roughly two orders of magnitude".
