Add four new functions to your convert.js library file that convert between pounds and kilograms, and also between square feet and square meters. Note that:

Question

1 kilogram = 2.205 pounds
1 square meter = 10.764 square feet

Once you have done this, modify your metric.html page so that the user can convert values using each of these functions.

Answer 1

```
function PoundsToKilograms(pounds)
// Assumes: pounds is a weight, measured in pounds
// Returns: the corresponding weight in kilograms
{
var kg;

kg = pounds/2.205;
return kg;
}

function KilogramsToPounds(kg)
// Assumes: kg is a weight, measured in kilograms
// Returns: the corresponding weight in pounds
{
var pounds;

pounds = kg * 2.205;
return pounds;
}

function SqFeetToSqMeters(sqFeet)
// Assumes: sqFeet is an area, measured in square feet
// Returns: the corresponding area in square meters
{
var sqMeters;

sqMeters = sqFeet/10.764;
return sqMeters;
}

function SqMetersToSqFeet(sqMeters)
// Assumes: sqMeters is an area, measured in square meters
// Returns: the corresponding area in square feet
{
var sqFeet;

sqFeet = sqMeters * 10.764;
return sqFeet;
}
