Any suggestions?

Hi everybody,

Does anyone have any suggestions too what i should add too my three way temperature converter?
Please don’t give me the answer just the suggestion thanks.

Code below:

Html:

<!DOCTYPE html>
Temprature Conversion

°C

=

°F

=

°K

```

Javascript:

function Temperature() {
	//this property get rewriten constantly as the result from all the maths that took place.
	this.kelvin = 294.15;
	
	// All the conversions
	this.setCelsius = function( celsius ) {
	    this.kelvin = celsius + 273.15;
	};
	this.setFahrenheit = function( fahrenheit ) {
		this.kelvin = ( fahrenheit + 459.67 ) * 5 / 9;
	};
	this.setKelvin = function( kelvin ) {
		this.kelvin = kelvin;
	};
	
	this.getCelsius = function() {
		return Math.round( ( this.kelvin - 273.15 ) * 10 ) / 10;
	};
	this.getFahrenheit = function() {
		return Math.round( ( this.kelvin * 9 / 5 - 459.67 ) * 10 ) / 10;
	};
	this.getKelvin = function() {
		return Math.round( this.kelvin * 10 ) / 10;
	};
	//end of final segment.
}

//resets the old values in the input boxes w/ the final results given.
function refreshForm() {
document.getElementById( “celsiusInputBox” ).value = ourTemp.getCelsius();
document.getElementById( “fahrenheitInputBox” ).value = ourTemp.getFahrenheit();
document.getElementById( “kelvinInputBox” ).value = ourTemp.getKelvin();
}
//carries out the refresh form function
function loadForm() {
refreshForm();
}

//Used too grab the values from the input boxes and also makes sure it’s a number not a string.
function enterCelsius() {
ourTemp.setCelsius( Number( document.getElementById( “celsiusInputBox” ).value ) );
}

function enterFahrenheit() {
ourTemp.setFahrenheit( Number( document.getElementById( “fahrenheitInputBox” ).value ) );
}

function enterKelvin() {
ourTemp.setKelvin( Number( document.getElementById( “kelvinInputBox” ).value ) );
}

//Global variable as a shortcut too the temprature object which we have created.
var ourTemp = new Temperature();

By the way everything is working.
