Numbers are displayed with localized values, but the form does not understand them.

Dear friends,

Using Drupal with French translation, some numbers are displayed with French equivalent.

Example:
Default MAX_ALLOWED_PACKET value : 1 Mo
(in French, 1Mo=1Mb)

Now, if I want to set this value to 3Mb, this quite confusing because the form does not allow "3Mo" (French).
On the converse, you can enter 3Mb. As a result, the interface then displays "3Mo". Confusing.

Would it be possible to enter 3 with a label set to Mb (with localized equivalent Mo).

The same problem applies for Php memory limit, which displays 32M on my install.
The user needs to enter 64M. It would be better to filter and allow only number with Mb label.
