New Grove TPH Rev 4

Just got one of these and threw it on a Mega, loaded the test sketch and

float pres = tph.readPressure()
Gives 13846489

So that isn’t Pascal’s (Pa) as stated on the wiki, so what is it?

A Gy-6B (BMP180) over a 3.3v I2C gives pressure at 986hPa for reference.

Temp and Humidity work fine and return correct values.
