capacitance = C Charge Q = C * V
charge = Ampere - second. So C = Amp-sec/Volt
Energy = work done in Joules = Q * V = Amp-sec- Volt
so Volt = Joule / Amp-sec
Resistance R = Ohm = Volt/Amp = Joule/Amp^2-sec
units of C R = Amp² sec²/Joule * Joule/Amp²-sec = sec. unit of time.
Units of C R^2 = Amp² sec²/Joule * Joule²/Amp⁴-sec²
= Joule /Amp²
charge = Ampere - second. So C = Amp-sec/Volt
Energy = work done in Joules = Q * V = Amp-sec- Volt
so Volt = Joule / Amp-sec
Resistance R = Ohm = Volt/Amp = Joule/Amp^2-sec

Units of C R^2 = Amp² sec²/Joule * Joule²/Amp⁴-sec²
= Joule /Amp²
