Speedometer ratio?

Does anyone know the "ratio" of the speedometer of a 3 1/2 Strada? I have a new-old-stock Veglia (mph) speedometer that I'd like to use on my project bike, but I'm not sure it's the correct ratio. It's marked: "1610 REV.s = 1M" on the back side. Thanks.

1610 metres in one mile, so I imagine that Veglia work from that for the mph speedo.

My friend Jarl checked his and the answer, yes, original and my "generic" Veglia are the same ratio.
One less piece to buy.

Surely this depends on the ratio in the wheel drive? One revolution of the cable drive should be 1 metre travelled?
