Lb means or stands for pounds. Weird right?
Your Lame Butt. Yeah I stalk you.
Lb stands for pounds.
Lb stands for different word e.g. Pound, load balancing etc. But according to the category of your question the most suited answer is Lb stands for Left back, a defensive position in football (soccer). Moreover it also stands for Linebacker, a position in American and Canadian football. May the answer is satisfactory.
As far as I know Lb stand for pound
Comes from the Latin Libra, which was a measure of weight. Thus Lb = pound and Lbs =pounds.
