See the following two sentences.
As per my knowledge it is right.
According to my knowledge it is right.
- Are both the sentences right?
- What is the difference and use of "as per" and "according to"?
Though I would understand both in written and oral communication, I find the first to be pretty odd. I wouldn't ever use it, and strongly prefer the second, "according to".
Why is this so odd? I looked a bit in the OED at the use of "as per" (odd in itself for combining two prepositions). It was first used in 1869 as a "slang" form "as per usual" by itself. I did however come across an entry that has a similar meaning to what you're looking for here: "by".
By. 3. a. According to; as stated, indicated, or directed by, as per advice, per instructions, per invoice, per ledger, etc. Usually preceded by as.
This was used as early as 1446 and as late as 1989. The difference here, I think, has been touched on: this meaning implies some obligation or requirement. No other entries seem to come close, and this matches my own mental lexicon for "per" and "as per". It just doesn't fit in this situation.
Both are bad English and are unnatural and incorrect uses of English as they are superfluous and add no additional or necessary information to the sentence. In general this type of mistake is common amongst Indian speakers of English. I believe, quiet ironically, that it is thought to add an air of intelligence to a statement. In fact, to a native speaker, it adds an air of pretentiousness that may serve to undermine the speaker in the eyes of the listener.
It clearly goes without saying that any statement you make is 'as per your knowledge' or 'according to your knowledge' unless stated otherwise. What else could possibly be the case.
What is the difference for example, between these statements with and without this structure...
A) "Manchester United won the Premier League in 2012"
B) "According to my knowledge, Manchester United won the Premier League in 2012" or B) "As per my knowledge, Manchester United won the Premier League in 2012"
In English we use 'according to...' to cite someone else. To cite oneself is clearly absurd, unless you are citing a paper you published, or something you have formally written. To cite your opinion or knowledge is meaningless.
We use 'as per' to refer back to something, such as 'as per our previous discussion' or 'as per the rules of the game'. Again, to use it to refer back to your knowledge appears ridiculous.
Regards and best of luck
Per means according to, so you can in fact say "per our agreement, you must...". The as in your first sentence is pleonastic, and sounds affected: I'd avoid it. The very common "as per usual" is a humorous prolixity.
Whether to use per or according to is the same as whether to use any archaic form or common usage. In some areas (e.g. law) it's more common to see per, so you could use it to set the tone as legalese.
Just to clarify...
'As per' is often used in legal discussions, for example regarding contracts. For example, "As per article 4 section 8..." and this has a different meaning to "According to article 4 section 8..."
For example if Article 4 Section 8 stated that you needed a doctors note in order to take sick leave you might say...
As per Article 4 Section 8 of our contract, I have attached a copy of my doctors note.
whereas with according to the meaning would be different.
According to Article 4 Section 8 I must supply a sick note in order to take sick leave.
Insofar as the answer refers to the two sample sentences: (As per my knowledge it is right /According to my knowledge it is right), I would tend to agree. However, as regards the general usage and difference between "as per" and "according to", I would disagree. The expression "as per" is simply a different register from "according to", and both terms are widely used in commercial and legal documents.
