Maybe this kind of conversion is required in other situations (calc, draw,
etc.).

So, it would be useful to add a defition of convertTwipToMm10() to 
`include/tools/UnitConversion.hxx`:
----
template <typename N> constexpr auto convertTwipToMm10(N n)
{
    return o3tl::convert(n, o3tl::Length::twip, o3tl::Length::mm10);
}
----


And if the defintion is accepted, the new code in
https://gerrit.libreoffice.org/c/core/+/131875 can be simply rewritten:
----
            // tdf#147989: workaround the accumulation of roundings
            aPageSize = awt::Size ( 10 * convertTwipToMm10( aTmpSize.Width() ),
                                    10 * convertTwipToMm10( aTmpSize.Height()
));
----
