I need help on building a box. The external dimensions are 445mm width, 343mm high, 308mm deep. I need these converted to inches. Also, the net internal volume is 47 L. What is this in cubic feet? This is external measurments using 3/4" material. Thanks for any info, Lewis

divide your millimeters by 25.4 this converts to inches. Then you can multiply all your results and divide by 12 three times to get cubic feet. so approx. 17.52in W x 13.50in H x 12.13in D. or approx 1.66 cubic feet.

Now I realize no ones to know how to do math so just go to google and type in '47 liters in cubic feet' and it will give you an answer.

I know it is Uber hard to read the site menu, located to your left. However, had you taken a look you may have found this magic page: https://www.the12volt.com/caraudio/boxcalcs.asp#rec Convert your numbers to inches and plug them in. Remember to account for woofer displacement and ports.

Thanks for the help. I had never seen speakers that gave the dimensions in mm. Now I know the formula to convert mm to inches. Thanks again. Lewis
