LONG POST
A unit switch should describe the same physical arrangement. The two-P2722H plan totals 1,339.8 mm with its chosen gap and margins. Using 25.4 mm per inch, that is about 52.75 inches. The illustrative 1,400 mm desktop width is about 55.12 inches. These displayed inch values are rounded; the calculator retains the underlying lengths.

Do not relabel a millimetre number as inches or replace a display’s physical outside width with its diagonal. If you copy rounded values into a different calculator, a small rounding difference is possible. Switching units inside this tool converts the entered lengths, including the gap and side allowances.

The physical conclusion is unchanged: this example has width left over, while depth and installation remain unassessed. Open the inch preset, switch back to millimetres and inspect the same plan. That is a conversion demonstration, not a universal desk recommendation, an ergonomic assessment or a tested workstation. Replace every illustrative allowance with the space you need.
