Some believe that the number 40 was used to symbolise a very large number, a number too large to count.
Only that when converted to Fahrenheit, the same number comes out: minus 40.
37.753 rounded to one significant figure becomes 40
40% of a number= 40% * the number= 0.40 * the number= 0.40 of a number

40 % as a number equals 0.40. 150.00(0.40) = 60, to the justified number of significant digits, since the number "40" is specified to only two such digits.

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
40 is no more significant than other numbers, and considerably less so than numbers such as π or e.
Rounded to one significant figure it becomes 40
If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number.If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.
