Using data recorded at centre-of-mass energies around 183 GeV and 189 GeV with the OPAL detector at LEP, the ratio R c W ≡ Γ (W-> cX)/Γ (W-> hadrons) has been measured from jet properties, lifetime information, and leptons produced in charm decays. A value compatible with the Standard Model expectation of 0.5 is obtained: R c W = 0.481± 0.042 (stat.)± 0.032 (syst.). By combining this result with measurements of the W boson total width and hadronic branching ratio, the magnitude of the CKM matrix element |Vcs| is determined to be |Vcs| = 0.955 ± 0.057.
