jQuery Toggle Fahrenheit Celsius

Question

I'm trying to create a weather app with the Open Weather Map API. I want to create a button that will allow you to toggle between Fahrenheit and Celsius. I've tried literally everything but I've gone back to the code I wrote before I tried putting a button in.

How could I implement this with my current setup?

<div class="container">

    <div class="jumbotron text-center" 
style="background-color: #00F0F8FF; font-family: 'Oswald', sans-
serif; color: black;">
        <h1>Local Weather App</h1>
        <h2><span id="town"></span></h2>
        <h2>Temperture: <span id="temp"></span></h2>
        <div id="weatherIconBox"></div>
        <h2><span id="weatherType"></span></h2>
        <button type="submit" id="btn1">F&#176;</button>
        <button type="submit" id="btn2">C&#176;</button>

    </div>
</div>

var getIP = 'http://ip-api.com/json/';
var openWeatherMap = 'http://api.openweathermap.org/data/2.5/weather'
$.getJSON(getIP).done(function(location) {
$.getJSON(openWeatherMap, {
    lat: location.lat,
    lon: location.lon,
    units: "imperial",    
}).done(function(data) {
    $('#town').html(data.name);
    $('#temp').prepend(Math.floor(data.main.temp) + '&#176;');
$('#weatherType').html(data.weather[0].description).css('textTransform', 'capitalize');
$('#weatherIconBox').prepend('<img id="weatherIcon"     src="http://openweathermap.org/img/w/' + data.weather[0].icon +     '.png"/>');

    });
});
