: Cov cim ntawm cov 'meter'

* Cov cim tau luam tawm txhua 1 'meter';

● Xim ntawm kev cim yog dawb, tab sis yog tias qhov kev rov hais dua yog qhov tsim nyog, qhov cim xim daj yuav tsum tau luam tawm tshiab rau ntawm qhov chaw sib txawv.
● Qee zaum yuav tso cai rau kev cim qhov ntev tsis meej yog tias ob qho cim ze ze ntawd meej;
● Ob qho kawg ntawm cov xov hlau raug kaw nrog cov hau kaw uas ua kom sov tau kom tiv thaiv dej nkag.
