Q:

How Can I Change the range of a range slider when I select an input radio or other?

I have a question and I hope you can help me with this:

 function GetGradeTemp () {
  var grades = $( "input[name='radios']:checked" ).val(); 
  $( ".c_f" ).text(grades); 
  var value1 = $("#tempMin").val();
  var value2 = $("#tempMax").val();
  $( "#minT" ).text(value1);
  $( "#maxT" ).text(value2);
}
$("input[name='radios']").change( GetGradeTemp );
$("#tempMin").change( GetGradeTemp );
$("#tempMax").change( GetGradeTemp );
GetGradeTemp();

$("#radio1").click( function() {
//
});

$("#radio2").click( function() {
//
});

  <div class="row">
        <div class="input-radio col s12 m12 offset-m5 offset-s5" style="margin-bottom: 0;">
                <input type="radio" id="radio1" value="C" name="radios" checked>
                <label clase ="radioLabel" for="radio1">C</label>
                <br>
                <input type="radio" id="radio2" name="radios" value="F">
                <label clase ="radioLabel" for="radio2">F</label>    
        </div>
      </div>

  <div class="row" id="inline2">
    <div class="col s12 m12 l12 offset-m3 offset-l4 temp_uv">
        <div class="quantity">
        <input type="number" id="tempMin" name="temp_min" step="1" min="-60" max="60" placeholder="-5 C" value="-5" />
        </div>
        <div class="line"><strong>—</strong></div>
        <div class="quantity1">
        <input type="number" id="tempMax" name="temp_max" step="1" min="-60" max="60" placeholder="40 C" value="40" />
        </div>
    </div>
  </div>
<br>
  <div class="row">
      <div id="temp_Slider_C"></div>
      
  </div>

in the code above I have two input type radio and two input type number. With the inputs type radio I can select the degree of temperature: °C or °F. In the input type number I can enter the temperature min and max. 
I would like to do convert the values from °C to °F or from °F to °C by clicking on the input radio options.
Example: If I have the temperature in °C and I do a click on the input radio with value=F, the values of temperature must change in the input type numbers...
Do you know how Can I do that with JS/jquery ? 
Note: 
C = (F - 32) * 5 / 9 (Celsius)
F = ((C * 9) / 5 ) + 32 (Fahrenheit) 

A:

you only need one change() for both radio .. like so
$('[name="radios"]').on('change',function() {
  // get this value for c or f
  var ThisVal = $(this).val().toLowerCase();
  // inputs val
  var value1 = $("#tempMin").val();
  var value2 = $("#tempMax").val();
  if(ThisVal == 'c'){
    $("#tempMin").val((value1 - 32) * 5 / 9);
    $("#tempMax").val((value2 - 32) * 5 / 9);
  }else{
    $("#tempMin").val(((value1 * 9) / 5 ) + 32);
    $("#tempMax").val(((value2 * 9) / 5 ) + 32);
  }
  GetGradeTemp ();
});

See the working code

function GetGradeTemp () {
  var grades = $( "input[name='radios']:checked" ).val(); 
  $( ".c_f" ).text(grades); 
  var value1 = $("#tempMin").val();
  var value2 = $("#tempMax").val();
  $( "#minT" ).text(value1);
  $( "#maxT" ).text(value2);
}
$("input[name='radios']").change( GetGradeTemp );
$("#tempMin").change( GetGradeTemp );
$("#tempMax").change( GetGradeTemp );
GetGradeTemp();

$('[name="radios"]').on('change',function() {
  // get this value for c or f
  var ThisVal = $(this).val().toLowerCase();
  // inputs val
  var value1 = $("#tempMin").val();
  var value2 = $("#tempMax").val();
  if(ThisVal == 'c'){
    $("#tempMin").val((value1 - 32) * 5 / 9);
    $("#tempMax").val((value2 - 32) * 5 / 9);
  }else{
    $("#tempMin").val(((value1 * 9) / 5 ) + 32);
    $("#tempMax").val(((value2 * 9) / 5 ) + 32);
  }
  GetGradeTemp();
});
