Create a speed converter

Create an input element that can convert one speed measurement unit to another.

First step - Add HTML:

<p>
  <label>MPH</label>
  <input id="inputMPH" type="number" placeholder="MPH"
  oninput="speedConverter(this.value)"
  onchange="speedConverter(this.value)"
</p>
<p>KPH: <span id="outputKPH"></span></p>

Second step - Add JavaScript:

Miles per hour to kilometers per hour:

/* When the input field receives input, convert the value from mph to kph */
function speedConverter(valNum) {
  valNum = parseFloat(valNum);
  document.getElementById("outputKPH").innerHTML = valNum * 1.609344;
}

Try it yourself
