Darrel has the basic formula here: http://www.picbasic.co.uk/forum/showthread.php?t=182

It's been a few years since that thread. Don't even remember doing it.

However, I think pt3rg asked the wrong question back then.
I'm sure he also wanted to convert the A/D reading from the sensor to a pressure value.
May be why he never came back.

With the formula for Vout ...
Vout = Vs*(0.009*P - 0.095)

For 10-bit A/D and 1 decimal, the reverse would be
P = ADC * 0.1086 + 10.6

-- OR --

ADCIN 0, ADval
P = ADval * 1086
P = DIV32 1000
P = P + 106

LCDOUT "P=",DEC P/10,".",DEC P//10,"kPa"

hth,

In case you didn't want 10-bit A/D with 1 decimal place in kPa ...

This should cover the other possibilities.
