MTH SMPH to MPH Scaling? | O Gauge Railroading On Line Forum

Adrian!OGR Forum Member

Random question...

Does anyone know the coefficient to go from real MPH to SMPH displayed on a DCS remote?

I'm building a high-frequency radar system (like the cruise control for a car) into my engine but it's calibrated in true physical MPH. If I wanted SMPH what do I multiply by?

Im asking if anyone knows:

1 MPH = ? SMPH

or

? MPH = 1 SMPH

Cheers!

1 MPH = 48 SMPH

or

1/48 MPH = 1 SMPH

Assuming you're talking O-scale (1/4" per foot). That is, the DCS remote is used for other scales (HO, S, G) in which case 48 would be replaced by 87, 64, and 32 respectively.
