Question Incorrect Google Description of Wikipedia Page

[manasan3010]

When you search for "Pressure Unit" You get the google Search result which shows in the description of Wikipedia Query " kg·m·s−2 " But In the actual Wikipedia Page it shows as " kg·m−1·s−2 " correctly. This creates distrust in Google's Results. The problem doesn't seem to be unscraped edits of Wikipedia Page because Google cache is also showing correct units and the unit hasn't changed in Wikipedia either. I am interested in knowing the possible cause for this issue

Likely a "typo" (typing mistake).

Or could be an error that was simply missed by an editor. m = m (to the first power) so an exponent of 1 is redundant and unnecessary and understood.

It has always been difficult to represent complicated formulas (and sometimes even simple ones) on one linear typing line.

And exponents can make the representation all the more difficult. And reciprocal numbers require the use of negative exponents which adds another complication to the physical representation while typing.

When typewriters were used, the typist had to slightly roll the paper downwards to type in an exponent. And, as necessary, include a preceding "-" to indicate a negative exponent.

(Read some old manually typed math papers and you will probably see exponents up and down or otherwise seemingly out of position.)

Most newer word processing apps support the use of formulas with respect to both symbols and structure.

Especially if the app itself uses some algorithm to "rewrite" the formula.

Just report the error and someone may correct it. And hopefully nothing else gets mixed up in the process....
