  You might be a few decimal places off.

    No, there are 1.4 billion cubic kilometres of water on earth (V_w = 1.4·10⁹ km³). Earth’s diameter is D_E = 12750 km. The volume of the relatively thin shell of water is approximately V_w ≈ π(D_E)² t. Inserting yields t ≈ V_w/(π(D_E)²) = 1.4·10⁹ km³/(π (12750 km)²) ≈ 2.74 km.

      In the original post, this was 2.7m, but has been fixed since then.

        That’s what quotes are for :)
