What does RS 65 Croer mean?

Rs means rupees, specifically Indian rupees in this case, which has the symbol ₹ and code INR. (Other countries have rupees as well, but that symbol is specifically for Indian rupees.)

One crore is 10 million in the Indian numbering system, see https://en.wikipedia.org/wiki/Crore.

Crore = 10 million, so 650 million rupees, or around $9M USD.

Tool I wrote to convert between Indian and American numbers.

65 crore = 650 million

Crore is equivalent to 10e6. In this case, that would evaluate to 650'000'000 INR.

> 10e6

Under scientific notation, you should strongly prefer to write 1e7. 10e6 is just begging for people to interpret it as 10⁶ rather than 10×10⁶ (10⁷).

But that's the definition, and every calculator's "engineering" mode shows it exactly like that, too. And usually you learn in middle school how to interpret that.

Here’s a photo with the calculator I used in middle school, showing exactly the specified number:

Curious. I don’t have a traditional calculator to hand, but tools like Rust, Python and Wolfram|Alpha are all turning 10e50 into 1e51.

https://en.wikipedia.org/wiki/Scientific_notation#Normalized... agrees with my memory that in normalised form the coefficient should be at least one and less than ten.

MeE isn't M^E, it's defined as M * 10^E.

And that’s what I was talking about from the start—10e6 is 10×10⁶, which is in normalised form 1×10⁷ or 1e7.

And the paragraph below the one you linked... https://en.wikipedia.org/wiki/Scientific_notation#Engineerin... is directly showing exactly the mode I'm using :)

Oh, I get it and see what’s happening. Kinda careless of me to miss it. Thanks for pointing it out.

I can see how it’s not obvious if you never learnt it, but especially in when working with the SI it’s incredibly useful and makes many hidden relationships quickly obvious.
