What is BS 1852 Code?

BS 1852 is British Standard 1852. In BS 1852 resistance code The letter R is used for Ohms and K for Kohms M for Megohms and placed where the decimal point will be.


At the end is a letter that represents tolerance Where M=20%, K=10%, J=5%, G=2%, and F=1%, D=.5% C=.25 B=.1%.
