We estimate the $\Lambda$-parameter in the $\overline{\mathrm{MS } }$ scheme<br />
for the SU(3) pure gauge theory with the twisted gradient flow method<br />
non-perturbatively. We obtain<br />
$\Lambda_{\overline{\mathrm{MS } }}/\sqrt{\sigma}=0.527(13)(10)$ and<br />
$r_{0}\Lambda_{\overline{\mathrm{MS } }}=0.605(15)(5)$ which are consistent with<br />
the known values.This demonstrates the validity of the present method.
