[1]

Oversample (OSR) modes internally combine and average samples to reduce noise.

[2]

Smallest bit change in register represents minimum value change in Pascals or meters. Typical resolution to signify change in altitude is 0.3 m.

[3]

Reference pressure = 101.325 kPa (sea level).

[4]

At 128x oversample ratio.
