javascript - Temperature conversion with openweathermap API -

i'm building weather app openweathermap api. app work have problem temperature converter still doesn't work.

here html:

   <div class='valign col s6 text-style'>        <div id="icontemp">            <div id="icon"></div>            <div id="temp"></div>        </div>          <div class='divider'></div><br>         <div class="text-style-details">            <div class="location"></div>            <div id="conditions"></div>            <div id="wind"></div>        </div>      </div> 

and javascript:

 <script type="text/javascript">       function toc() {         var strin = parseint(temperature);          if(isnan(strin)) {           alert("not number");         } else {           var f = parsefloat(strin);           var c = (f - 32) * 5/9;            var r = math.round(c * 100)/100;           parseint(temperature) = r.tostring();            }     }      function tof() {         var strin = parsefloat((temperature).tofixed(1));          if(isnan(strin)) {           alert("not number");         } else {           var c = parsefloat(strin);           var f = (c * 9/5) + 32;            var r = math.round(f * 100)/100;           parsefloat((temperature).tofixed(1)) = r.tostring();            }     }  $(document).ready(function() {      getlocationdata();      function getlocationdata() {       $.get("http://ipinfo.io", function(location) {         console.log(location);          $('.location')           .append(location.city + ", ")           .append(location.region);          var units = getunits(location.country);         getweatherdata(location.loc, units);        }, "jsonp");      }      function getweatherdata(loc, units) {       lat = loc.split(",")[0]       lon = loc.split(",")[1]        var appid = "&appid=123456abcde"        var url = 'http://api.openweathermap.org/data/2.5/weather?lat=' + lat + '&lon=' + lon + "&units=" + units + appid;        console.log(url);        $.get(url, function(weather) {         var winddir = winddirection(weather.wind.deg);         var temperature = weather.main.temp;         var unitlabel;          if (units === "imperial") {           unitlabel = "<a href='#'>f</a>/<a href='#' onclick='toc()'>c</a>";           // temperature = parsefloat((temperature).tofixed(1));         } else {           unitlabel = "<a href='#' onclick='tof()'>c</a>";           // temperature = parseint(temperature);         }          // temperature;          // temperature = parseint(temperature);         // temperature = parsefloat((temperature).tofixed(1));            console.log(weather);          $('#icon')           // .append("<img src='http://openweathermap.org/img/w/" + weather.weather[0].icon + ".png'>");           .append("<i class='wi wi-owm-"+weather.weather[0].id+"'></i>");                    // <i class="wi wi-owm-200"></i>          $('#temp').append(temperature + "&deg; " + unitlabel);         $('#conditions').append(weather.weather[0].description);         $('#wind').append(winddir + " " + weather.wind.speed + " knots");        }, "jsonp");      };        function winddirection(dir) {       var rose = ['n', 'ne', 'e', 'se', 's', 'sw', 'w', 'nw'];       var eightpoint = math.floor(dir / 45);       return rose[eightpoint];     }      function getunits(country) {       var imperialcountries = ['us', 'id', 'sg', 'my', 'bs', 'bz', 'ky', 'pw'];        if (imperialcountries.indexof(country) === -1) {         var units = 'metric';       } else {         units = 'imperial';       }        console.log(country, units);       return units;     }    }); </script> 

the app pict:

i created function toc (convert f c) , tof ( convert c f), when click label error message "uncaught referenceerror: toc not defined". want app temperature value change when click c (celcius) , f (fahrenheit).

any appreciated greatly, thank you.

although writing kind of functions training good, answering main question according openweathermap api unit conversion support:

you can pass: &units=metric api call in order temperature in celsius, this:

api.openweathermap.org/data/2.5/weather?lat=latitude&lon=longitude&units=metric&appid=your_api_key 

here info official documentation:

units format description: standard, metric, , imperial units available.

parameters:

units metric, imperial. when not use units parameter, format standard default.

temperature available in fahrenheit, celsius , kelvin units.

for temperature in celsius use units=metric temperature in fahrenheit use units=imperial

examples of api calls:

standard api.openweathermap.org/data/2.5/find?q=london

metric api.openweathermap.org/data/2.5/find?q=london&units=metric

imperial api.openweathermap.org/data/2.5/find?q=london&units=imperial
