Tá 1 milliméadar cothrom le 0.0032808 troigh:
1 mm = 0.0032808 ft
Tá 1 milliméadar cothrom le 0.03937 orlach:
1 mm = 0.03937 in
Tá an fad iomlán d in orlach (in) cothrom leis an bhfad d i milliméadair (mm) arna roinnt ar 25.4:
d (san iomlán) = d (mm) / 25.4
Tá an fad d i gcosa (ft) cothrom le luach urláir an achair d in orlach (istigh) arna roinnt ar 12:
d (ft) = ⌊ d (in) iomlán / 12⌋
Tá an fad d in orlach (in) cothrom leis an bhfad iomlán d in orlach (in) lúide 12 oiread an achair d i gcosa (ft):
d (in) = d (san iomlán) - 12 × d (ft)
Tiontaigh 400 milliméadar go troigh + orlach:
d (san iomlán) = 400mm / 25.4 = 15.748in
d (ft) = ⌊15.748in / 12⌋ = 1ft
d (in) = 15.748in - 12 × 1ft = 3.748in
d (ft + in) = 1ft + 3.748in
