Hmmmm...I guess I meant deg C, since that's what I wrote.
But you are correct. Not much difference C to F at that temperature.
But I also mentioned "around" because, of course, it may vary slightly with gasoline type, brand (additives) and atmospheric pressure (and, hence, altitude).
A common mistake is to confuse flash point with auto ignition temperature. Very different.
