Hi,

have connected my SG measuring device with ubidots, the thing sends a two decimal tilt factor and an SG, which is for some reason rounded to increments of 10 (thus useless) with the tilt values and and the cut of points I´ve derived a polynominal formula which should return the correct Plato factor. then using the plato to Gravity formula I´ve added the following formula (1+(0.018642*tilt*tilt-1.628142*tilt+37.531996)/(258.6-227.1*(0.018642*tilt*tilt-1.628142*tilt+37.531996)/258.2))*1000

where the tilt variable nicely highlights. However after receiving tilt values I still see no calculated sg value.

what am I doing wrong here?

is it the brackets or the tilt*tilt to get a squared value?

any help would be appreciated.

Yoeri.
