Ah, the mass/weight confusion. Agree with you on that. And no, most such writers don't handle unit conversions in anything like an intelligent way (and I've seen far worse examples, some going to 2 or 3 decimal places ..)
Sometimes I wish more people understood the difference between mass and weight, and the difference between energy and power. It would cut down on some of the gibberish.

The same editors also convert rocket thrust from pounds (of force) into kilograms, because they don't know that pounds can measure mass or force and these ARE NOT THE SAME THING! In respected scientific publications I see statements such as "the 100 pound (45.3 kilogram) rocket thrusters..." when they SHOULD have written "the 100 pound (400 Newton) rocket thrusters....".
