${\displaystyle m=\int \lambda \mathrm {d} \ell }$

${\displaystyle m=\iint \sigma \mathrm {d} S}$

${\displaystyle m=\iiint \rho \mathrm {d} V\,\!}$

${\displaystyle \mathbf {m} =\mathbf {r} m\,\!}$

अक्षसापेक्ष विविक्त वस्तुमान ${\displaystyle x_{i}\,\!}$:

(इतर चिन्हेही वापरली जातात.)

${\displaystyle \mathbf {m} _{\mathrm {i} }=\mathbf {r} _{\mathrm {i} }m_{i}\,\!}$

विविक्त वस्तुमान:
${\displaystyle \mathbf {r} _{\mathrm {com} }={\frac {1}{M}}\sum _{i}\mathbf {r} _{\mathrm {i} }m_{i}={\frac {1}{M}}\sum _{i}\mathbf {m} _{\mathrm {i} }\,\!}$

अखंड वस्तुमान:
${\displaystyle \mathbf {r} _{\mathrm {com} }={\frac {1}{M}}\int \mathrm {d} \mathbf {m} ={\frac {1}{M}}\int \mathbf {r} \mathrm {d} m={\frac {1}{M}}\int \mathbf {r} \rho \mathrm {d} V\,\!}$
