Or use a TDR like the Tektronix 7S12. RG400 (solid PTFE dielectrice IIRC) in my experience typically comes out at about 8.6" per nS which is slightly at odds with the published propogation speed of .69 which would suggest 8.28". The 5nS cables I made up not long back are almost exactly 43" long.
RG58 has a published propogation velocity of .66 (8" per nS) but tends to vary rather more in characteristics (electrical length versus measured length).
