Áireamhán tiontaithe feet (ft) go milliméadar (mm) agus conas a thiontú.
Iontráil an fad i gcosa (ft) agus brúigh an cnaipe Tiontaigh :
Tá 1 chos cothrom le 304.8 milliméadar:
1 ft = 304.8 mm
Tá an fad d i milliméadair (mm) cothrom leis an bhfad d i gcosa (ft) uaireanta 304.8:
d (mm) = d (ft) × 304.8
Tiontaigh 2 throigh go milliméadair:
d (mm) = 2ft × 304.8 = 609.6mm
