Quick query here, and purely a question
My website says the wind is F3 a light breeze at 18mph, just checking Wikipedia (yeah I know how wonderfully accurate it is
) says that 18.3 is an F4 Moderate breeze, which is correct?

On that screen shot, your average wind speed is 10.4 mph, which is F3. The Beaufort scale applies to average wind speed.

Quick question as to why F has been used to represent "force"?
Beaufort force is referred to using B in calculating equations
The Saffir-Simpson scale uses S and the Fujita Scale or Enhanced Fujita scale uses f or F or EF, depending on what is being estimated.
I just think that the term F3 has potential to be misinterpreted.

Because that is the form I have seen used by experienced meteorologists in the UK, e.g. Dave Wheeler (who provides this forecast):
http://www.orcadian.co.uk/weather-2/
"Generally light winds across Orkney with a F2-3 SE to E’ly wind across Shetland."
"A F5 E’ly breeze may bring a few mist or fog patches to some eastern coasts."
The same form is used (again, by experienced meteorologists, including those who work for the UK Met Office) in the uk.sci.weather newsgroup, which is where I learned much of what I know about the weather.
