The conversion between metric and English units is easy to remember.

One inch equals 2.54 centimeters exactly.

By calculation you can make up your own conversion tables to however many decimal places you wish.

For example,
5km x 1000 = 5000m
5000m x 100 - 500000cm
500000cm /2.54 = 196850.39 inches
196850.39 inches = 16404.20 feet
16404.20 /5280 = 3.106856 miles

Put your computer to work using 1 inch = 2.54 cm. It works.

I work with at least 6 significant figures, and only round off the final answer. You are right - intermediate rounding is a bad idea.

Here it is worked out:

        }
        
                $('#{%=id%}Okay').on('click', {%=id%}Okay_click);
        })();
    </script></li></ul><a href="javascript:void(0);" class="close-reveal-modal" aria-label="Close Modal">&#215;</a><div class="last-modal-focus focus-utility-element" tabindex="0"></div>

        (function() {
            {%=id%}Popup = new SS.Popup.ModalPopup('{%=id%}');
        })();
    </script>
