hello I have to change this resistance of 5w R 12 j is open, and I do not know if it is 0.12 ohm oh 12 ohm confuses me the start R I need help

Cordial greetings, friend Cris the resists with encapsulation of porcelain work with alphanumerical code of the series E-12 to classify these resistances, as says the companion Jjn is of point twelve ohms since in this alphanumerical code the R is equal to the comma or decimal point, J is the tolerance of 5%, if we have 5WR12J, it means a resistance of 0.12 ohms to 5% of 5 watts, with this tolerance the resistance when measuring it can be between the normal values ​​of 0.11 ohms or 0.12 ohms which will be normal. regards
