So to have a “percentage difference,” I would look for 2 percent (ratios) and take the difference from them as fractions. For example, the percentage difference between 30% and 50% is 20%. But you don`t have two reports, you only have two big numbers. Time is required for percentage changes. First, take a step, then take a second step. Then assess the difference and present this difference as a percentage of the starting value. In particular, if you said that the value goes from 211373 to 185420, the change is 185420 – 211373 – -25953. As a percentage of the starting value, it is -25953/211373 – 100 – -12.28%. Since it is negative, I could say that there is a decrease of 12.28 per cent. Note that the term (211373 – 185420) is the difference between the two digits and the term (211373 – 185420) /2 is the average of the two digits. This gives us a decimal point that we then have to multiply by 100% to convert it into a percentage. Gabriel (the person who answered your question first) is a physicist.

The percentage difference between two numbers doesn`t really have any specific mathematical significance, so the context for which you use it is, hopefully, the physical sciences. Often people are confused by the percentages. Really, all they are fractions (percentage means per cent, so 100 is the denominator: 13.1% – 13.1/100). And fractions are only relationships between two numbers: a counter and a denominator. The % difference between two figures is the absolute value of the difference between the two figures, divided by the average of these two figures, multiplied by 100%. This is the % difference between these two numbers 211373 – 185420 Multiply the quotient value by 100 to get the approval percentage of the equation. You can also move the decimal place to the right two places, which offers the same value as multiplying by 100. Another aspect that people are asking for is the percentage change. This is the modification of an early value to a later value, and conventionally it is done in relation to the previous value.

This means that the previous value is the denominator. You did not say if your comparison was a previous/later situation, but if 185420 was the later of the two, then you could say: % difference is similar, but different from “% error”.”
