lol, as long as it's not space mission, you are fine :biggrin:
It is a cluste rfuck to have to to deal with 2 units.
The frustration that I have to deal with daily is that all architectural drawings are in scale metrics, mechanical specs can be 1/2 in metric and 1/2 in imperial specially volume, pressure, and flow rate.
It is a pain in the arse that I have to constantly convert from one system to another, and then have all machine made in the US with specs in what ever imperial scales that the manufacture feels like printing it in. Then there are curve balls that I have to deal with is that some machines that are from the EU that are in metric that have to be mate into the rest of the system that are in imperial.
Not only that I have to deal with machine that have different voltage & HZ rate, I have to deal with flow/pressure/temperature all in different measurement. Sometime it is such a cluster fuck that I have to take a day to clear my mind so that I don't make mistake with conversions.

No measurement system is intrinsically more accurate or precise than any other.I also prefer metric for physical measurements as it is more accurate
Fahrenheit isn't more precise than celcius, it just has smaller intervals between degrees.
F is retarted and it should be not used.
Why?
What does the 0 and 100 represent in Fahrenheit?
Answer: Some random bullshit: Praise the lord, Darwin is wrong, Universe is 6000 years old.
What does the 0 and 100 represent in C?
Answer: Freezing and Boiling Point of Water, the most common substance in our world (our body is 70% water). Water in turn is composed out of the most common substance in the Universe which is hydrogen.
C wins. Only stupid US rednecks use F.
Kelvin is the only system that actually makes sense. I prefer C because it's just Kelvin with a reasonable offset (no scaling factor) to make every day use easier.
(yeah I know C came first but I like to think of it like this)

For that reason alone the US Customary Units should be scrapped.
0 F is the freezing point of salt water. Which is actually what our body contains. 0 C is the freezing point of fresh water. And knowing the boiling temperature of water is fairly useless for 99% of people. You turn on the stove and leave it on until the water boils.
F wins. Only effete Euro-trash and communists use C.
0C = water freeze
100 = water boil
1 cubic meter water = 1000 Litter of water = 1000 Kilograms
1 Metric tonne = 1000 Kilograms
1 Kilometer = 1000 Meters = 1,000,000 Millimeters
1 Joule = 1 Newton = 1 Watts/Second
1 Kilowatt = 1000 Watts
1 Kilopascal = 1000 pascal = 1 Kilonewton/square meter
32F = water freeze
212F = water boil
1 cubic foot water = 7.48051945 gallons = 62.42796 pounds = 998.84736 ounces
1 mile = 1760 yards = 5280 feet = 63360 inches
[SIZE=-1]1 ton = 20 [/SIZE][SIZE=-1]hundredweights = [/SIZE][SIZE=-1]80 quarters = [/SIZE]160 stones = 2240 pounds = 35840 ounces
1 acre = 4 roods = 160 poles = 4840 square yards = 43560 square feet = 6272640 square inches
Can you see how retarded the imperial system is, and I'm not going to bother with BTU, candle power, horses, PSI, etc...
PS. You are a dinosaur that will soon extinct because the world move on to something that is easier to use thus minimizes calculation error.
I was born in the Metric system, but living here in Canada we are force to use the retarded imperial system because the stupid/old American cant learn new tricks.
you win.
for presenting a clear solution, but more importantly for understanding the point of the thread.
everyone else is too busy trying to explain that decimals can be used in Celsius to increase precision, because apparently they are that much smarter than i am.
i had no idea that you can use decimals with C until they schooled me.
we have a winner. Now who out there is stubborn enough to argue against igas's winning point?
Celsius is NEAR 0 for freezing water (even in ideal lab conditions, it isn't exactly 0°C), and is rarely at 100 for boiling water (it is often several degress off due to air pressure variations). And the temperature for both depends a lot on the number of nucleation points available (water will stay liquid far below 0°C if there are no nucleation points). Plus using water for your calibration is arbitrary anyways. Why not ethanol or any other common chemical?
Fahrenheit at least has the advantages of:
1: being weather related (most of the world is between 0°F and 100°F and extremes on either side of that range are a health hazzard).
2: being nicely tuned to heath. A temperature above 100°F is a fever. Why would you want to memorize 38°C when 100°F is easier? Note: using human health is just as arbitrary as using water.
3: matching the precision of human feeling. We can tell the difference between temperatures that are roughly 1°F apart. A 1°F change in the outside temperature or the thermostat is just enough to notice. Like the OP said, 1°C is just too coarse of a temperature range and you are forced to go with decimals.
But, in the end both suck. Neither have an absolute zero at 0. Rankine is the best of all worlds. A true zero and temperature intervals that match human touch.
Fahrenheit is fucking retarded. No wonder the US is still stuck using that archaic system.

Then I'd like to see a study that shows how much time is wasted, and how many things are botched, based on the time spent on converting (or forgetting to to so) from one unit system to another.Seriously, why the fuck do you guys feel so strongly about having to convert America to a SI nation?
If people feel like using Fahrenheit, lbs, and miles in their everyday life, let them. In sciences, medicine and engineering, most of the labs have already switched to fully metric systems. Don't tell me that this isn't enough. People still partially use imperial units in some parts of England, Canada, Hong Kong, etc. Petroleum is still sold in terms of gallons in a lot of countries.
In addition, the cost of conversion is prohibitive. It costs NASA an additional USD$370M to retool and use the metric systems to manufacture and engineer their space project. Think about how much it would cost in the rest of the country.
Sounds like a perfect argument for Celsius, with its "larger" degrees.C sucks, and UFC in was in England, they suck with that Stone shit they use. Who the fuck weighs themselves based off that? I weigh 14.2857 Stone according to the converter I found, that's the gayest shit ever.
F for life, knowing the freezing or boiling temp of water is utterly useless. When I need to boil water I put in on the stove until it bubbles, you can't burn water so it doesn't matter. As for freezing I put it in the freezer until it's... frozen! What novel concepts.
Out of those, let's just count the companies that do direct business with the US:
Royal Dutch Shell (458)
ExxonMobil (443)
BP (367)
Chevron (263)
ConoccoPhilips (231)
Toyota (204)
GE (183)
Volkswagen (167)
GM (149)
Ford (146)
(number) indicates gross revenues in billions of USD. All of those sum up to be ~2600 billion USD.
Let's say that it will cost 5% of overall revenue to retool all of their existing imperial units systems to SI. Note that for NASA, whose operating budget is USD $17B, the retooling cost of one project is USD$370M, it works out to be roughly ~2%; so an overall 5% estimate should be reasonable for the entire organization and let's say it will be for all companies.
5% of USD$ 2600B is USD$130B. For comparison, this is about as much as 89% of Ford's gross revenue last year, 9% of Canada's nominal GDP, 14% of Australia's nominal GDP, 100% of New Zealand's nominal GDP, and 3 times the NET profit of ExxonMobil.
Now, I'm sure if somebody wants to foot the bills of retooling, America will happily oblige. Until then, people from other countries whose economy and welfare enjoy the benefits of R&D and engineering done by American firms should probably let it go.
