Hi everybody,

I just spent about 15 minutes googling and could not find simple formulas I need to implement for conversions of kg into pounds or stones and pounds, pounds into the other 2 and stone and pounds into the other two.

Here is what I started to write but I can not find the formulas to use:

 $scope.updateWeight = function(weight1, weight2, units)
            {

                switch (units) {
                    case 'kg':
                        $scope.currentGuest.weightG = weight1 * 1000;
                        $scope.currentGuest.weight = Math.round(weight1 * 2.20462); // weight in pounds
                        $scope.currentGuest.weightStone = Math.round(weight1 * 0.15747); // weight in stones
                        $scope.currentGuest.weigthLbs = // remainder for stones/pounds
                        break;
                    case 'lbs':
                        
                        break;

                    case 'stones': // stones and pounds
                        break;
                }
            }
