Divide by 236.59 for a close estimate; the calculator above uses the full factor of 0.004227.

Precision and rounding

One millilitre is exactly 0.004227 US cups under the current definitions of both units, so the only judgement call is how many digits you keep. Two decimal places is already finer than most household scales and tape measures can read, while engineering and medical work usually keeps the full factor and rounds once at the end rather than at every step.
