The Einstein field equations which relate physical quantities to curvature are:
Rμν−12gμνR=8πGTμνRμν−12gμνR=8πGTμν
The tensor which contributes to the curvature is the stress-energy tensor TμνTμν which contains quantities such as energy density, shear stress and pressure. The tensor itself is computed from the Lagrangian which governs the matter present. In field theories, we see via Noether's theorem that the stress-energy tensor is in fact the conserved current due to invariance (up to a total derivative) under global spacetime translations.
