- Purpose of use
- Calibrate BMP280 sensor, which shows 1012 at 110m on Solta island. There are nearby stations 20km away: Split (Marjan) measuring 1024.3 and Hvar island with almost the same. Reduced value was 1024.9 which may be in the precision range. Thanks.

- using the shown formula i come up with a different answer with the same inputs. using p=1012.265, h=105, t=17.19 the website calculates 1024.84. running the formula by hand and in excel i get 1004.6341. any ideas where the error is?
- from Keisan
- We have tried it in excel, but the result was same.(1024.84)
