    Re: Converting cm/s to mph

    Hi,

    You start with:

    3cm/s * 60s/min ---- Seconds cancel and we're left with minutes
    180cm/min * 60min/hr ---- Minutes cancel and we're left with hours
    10,800cm/hr * 1ft/30.48cm ---- Centimeters cancel and we're left with feet
    354.33ft/hr * 1M/5,280ft ---- Feet cancel and we're left with MPH

    0.0671 MPH

    So yes, you are correct!

    I hope this helps.
