Broomiarv iseloomustab uuritava aine küllastumatuse astet, nii nt bensiini jt vedelkütuste korral on broomiarv oluline mõõtesuurus, mis näitab sisuliselt olefiinide sisaldust.
The magnitude of bromine number is simply an indication of the bromine reactive constituents, not an indication of the constituents; the bromine number is expressed as g of bromine (Br2) able to react with 100 g of product.
