If you are driving across the border into Canada, it is difficult with the road signs in KPH
values. In Canada, the Kilometers Per Hour scale is used to measure speed. In the USA, the
Miles Per Hour scale is used. For example, a speed limit of 50 MPH in Vermont is 80.47 KPH
in Montreal. A speed limit of 60 KPH in Toronto is 37.28 MPH in Buffalo, NY. You’d like
your computer or smartphone to convert between the Speed limit signs so you do not get a
ticket.
