Re: New thing I hate? Questing on Cross Realmsaid by DarkLogix:Wrong LBS is weight not Mass
a given object wouldn't change in mass if moved from Earth to Mars but the g (acceleration due to gravity) would be different, even not knowing the exact g of Mars one would know its lower than the g of Earth.
So with W=mg if the mass of the object is the same but the g is lower then the weight will be lower.
So to achev 2200lbs on Mars would require a larger mass than it would on Earth.
And as lbs is a measure of WEIGHT not MASS. No. Pounds are mass. Pound-force is weight. kg are like lb N are like lbf Another reason I hate our stupid system. |

Another reason I hate our stupid system. To be fair, the term "pound" is used in a very confusing fashion, sometimes as a unit of mass, and sometimes as a unit of force/weight. » en.wikipedia.org/wiki/Po ··· d_(mass)» en.wikipedia.org/wiki/Po ··· _(force)The usual unit of mass associated with the English system (at least that I am familiar with), is the slug: » en.wikipedia.org/wiki/Sl ··· g_(unit)As a scientist (biochemist) living in America, I would be ecstatic if all countries went full metric. I am much more familiar with metric volume measurements, for instance. Metric distances aren't a big problem for me either. (Weather reports given in C instead of F would take some getting used to, though.) Plus, no more having to remember "8 ounces per cup, 2 cups per pint, 2 pints per quart, 4 quarts per gallon" garbage. Just move the fricking decimal place and you're done. Don't even get me started on tablespoons versus teaspoons. However, I doubt that the US will ever switch to metric. Too many people with not enough brainpower to convert the "2 cups of flour" in their biscuit recipe to a metric unit. Multiplication is HARD. |

Same thing with ounces versus fluid ounces. I've had to correct a few people when they've pulled out a measuring cup to get 12 ounces of chocolate chips, for example. Granted, it is used in a confusing way, but I was more concerned with the assertion that pounds are weight and only weight. I converted myself back in my high school years ('05 was my last year) and haven't looked back. I drive a Civic with an all digital dash. It stays in metric. I'd be okay with getting 480 mL of flour out. |

What if I want chocolate chips by volume not by mass? |

That's cool, but the recipe called for them by ounces. Typically, it'd say 1 1/2 Cup for a volume measure of 12 fl oz. |
