oops...poor placement of ellipsis...did not use properly...meant .15 kg ...learned something new today but the trailing off of my train of thoughts worries me...I will attibute it to older age.

An ellipsis (...) is a set of three periods that indicates the omission of words from quoted material, hesitation, or trailing off in dialogue or train of thought. An ellipsis should have spaces before, between, and after the periods.
