New air conditioners clear a global-warming limit on 2013 figures

Singapore bars household air conditioners whose refrigerant exceeds a global warming potential of 750. The regulator publishes R-32 at 677, sourced to the IPCC's 2013 assessment; the current assessment says 771. The limit sits between the two, and the same thing has happened independently in the United States at a limit of 700.

Two poison services disagree about how much chocolate your dog can eat

Britain's Veterinary Poisons Information Service answers in grams of chocolate per kilo of dog. The ASPCA and Merck line every calculator uses answers in milligrams of theobromine. Converted through USDA composition data the two rules cross each other — and the highest-theobromine thing in most kitchens is not a bar of chocolate at all.

One Checkbox Multiplies Your Ink Bill by Thirteen

Cartridge yields are rated against test pages averaging about 5 per cent ink coverage. We printed five of our own pages twice — once with Background graphics on, once with it off — and the same document used between 7.5 and 13.8 times more ink depending on nothing but that checkbox. Printed normally, every page came in under the rated coverage.

How Many Ounces in a Cup? Eight — and That Is Why People Get It Wrong

Eight is correct, for one specific cup out of six in ordinary use. The largest is 57.9% bigger than the smallest, the cup in a Singapore or Malaysian drawer is not the American one, and the two traps run in opposite directions: the imperial cup is larger than the US cup while the imperial fluid ounce is smaller. Five steps to the right number, and when to stop converting and weigh instead.

How to Work Out How Much to Feed Your Dog or Cat

Almost every feeding mistake starts with the weight you type in. Use the animal in front of you and the sum returns the calories that keep it exactly the size it is. Six steps, in order, from body condition through to what goes in the bowl — and what the one substitution is worth: on a Labrador carrying a fifth too much, about a cup and three quarters of food a day.

House Calculations for a Tropical Climate

Ask this site how much air-conditioning a Petaling Jaya bedroom needs and, until this week, you got two different answers — 5,000 BTU from one calculator and 9,000 from another. Settling that argument meant tracing the low number back to a US rule of thumb that assumes an insulated house in a temperate country, and finding it was about a third of what installers here actually fit. What a tropical room really needs, why an oversized unit leaves it cold and damp rather than comfortable, what a ceiling fan is worth in degrees, and why the 601st kilowatt-hour on a Malaysian bill costs RM32 against a headline rate of 44 sen.
