This thesis presents the first experimental calibration of the top-quark Monte-Carlo
mass. It also provides the top-quark mass-independent and most precise top-quark pair
production cross-section measurement to date. The most precise measurements of the
top-quark mass obtain the top-quark mass parameter (Monte-Carlo mass) used in simulations,
which are partially based on heuristic models. Its interpretation in terms of mass
parameters used in theoretical calculations, e.g. a running or a pole mass, has been
a long-standing open problem with far-reaching implications beyond particle physics,
even affecting conclusions on the stability of the vacuum state of our universe. In
this thesis, this problem is solved experimentally in three steps using data obtained
with the compact muon solenoid (CMS) detector. The most precise top-quark pair production
cross-section measurements to date are performed. The Monte-Carlo mass is determined
and a new method for extracting the top-quark mass from theoretical calculations is
presented. Lastly, the top-quark production cross-sections are obtained - for the
first time - without residual dependence on the top-quark mass, are interpreted using
theoretical calculations to determine the top-quark running- and pole mass with unprecedented
precision, and are fully consistently compared with the simultaneously obtained top-quark
Monte-Carlo mass
