In ABAQUS, if I use m as length and MPa as the unit of Stress. what will be the unit of Force and density please?

RE: Units
Force in Newton
Density in tons/mm³
RE: Units
Length = meter
Time = seconds
Mass = 1E6 kilogram = 1 kt (kiloton)
Derived units:
Stress: 1 MPa
Force: 1E6 N = 1 MegaNewton
Density: 1e6 kg/mm³ = 1 kt/mm³
RE: Units
Stress in MPa = N/mm^2 = MN/m^2, Hence Stress is MN/m, Then Force = MN as you stated.
time = s, Gravity is MN/s^2, hence Gravity = 9.81E-6 MN/s^2
Pa = kg/ms^2, so 1 MPa = 1Mkg/ms^2 = 1 ton/ms^2
so if an structure weight 1 ton, the input in ABAQUS is 1.
RE: Units
If a structure have 1000 kg/m^3 = 1 ton/m^3. so the ABAQUS input is 1.
Could anyone kindly confirm that this is correct?
RE: Units
Mass unit is kt. So a structure of 1 ton = 1000 kg is to input as 1e-3
Density input is kt/mm³, which is equivalent to 1e6 kg/mm³ = 1e15 kg/m³. So 1000kg/m³ is to input as 1e12
