Restore the original standard gravity factor

Browse Source 
The Uwatec/Scubapro dive computers are confirmed to internally use the
approximated standard gravity (10.0 m/s²) for the depth conversion.
Allthough this is technically wrong, users expect to get the same depth
values as their dive computer shows.

This partially reverts commit cfc9ddc380bdc5616893fc2af4e05204b5500ea2.
