adamkerrnz -> metric is easier!!! (9/22/2004 4:14:54 AM)

agree or disagree?

With the metric system it is a lot easier.

When i mix my fuels i dont need many calculations
e.g.
i want 15% nitro with 20% oil
ok... i want to make a litre of fuel so 1 litre = 1000ml

easy = 150ml nitro = 15%
200ml oil = 20%
650ml methanol =65% [:D]
All this adds up to 1000ml or a litre and wow we have 100%

i really do not get the imperial system at all!!!

Of course the metric system is easier but it's difficult to change old habits. The USA is the only country NOT using metrics (apart from two tiny African countries). Actually this isn't quite correct, the USA does use metrics in one area...money! It's only a matter of time before the USA falls in line with the rest of the world and converts fully to metrics and then there'll be a lot more home brewed fuels :D

adamkerrnz,

For a little amusement take a look at the "Making Fuel" thread elsewhere on this forum. Somebody was measuring with cups. I suggested the metric system. Then a Laboratory Scientist got involved and suggested measuring in "Glugs" Really, Glugs. It deteriorated from there.

The U.S.A. is slowly converting to metric. Automobiles are built to the metric system for the most part. But many bolts such as the wheel lugs are American Standard. Some consumer foods are metric, soda is sold in liter's but milk is sold in quarts and gallons. The aerospace is converting to metric. I think consumer products partially swithched about 20 years ago and haven't changed since, but many hard goods are switching over with time. Metric is much easier, as long as you don't have to convert back and forth.

Totally topsie turvey here in the UK, you can buy a pint of beer but not a pound of fruit or veg. You drive in miles but the service intervals of your car are in Kms. Cable can be bought by the metre but cloth is sold by the yard!!

For a long time the USA has been at the forefront of invention, innovation, and development of new ideas. "Why is this?", you ask. The answer is that the mental exercise we get from dealing with our nonsensical measurement systems has helped us to develop large, efficient fast brains. As the metric system becomes more and more common in the USA, we are getting mentally flabby and dropping down toward average level. [:D][:D][:D][:D][:D]

Please understand that I am joking, and mean no offense to anyone with a metric[8|] brain.

ROFLMAO!!!!!![:D][:D][:D][:'(][:'(][:D][:D][:D]

Hey JIm even my metric brain found that hilarious



Test005 -> RE: metric is easier!!! (11/5/2004 8:48:00 AM)

Well you American still got it easier than us Europeans.
You're brought up using the Imperial system and many have easily learned the Metric system because of it's simplicity and logic.
We Europeans that are brought up with the Metric system do have soem difficulties converting things into Metric from Imperial.
Many posts on this forum is gallons, quarts, inches...Allright, that's OK, but then you start coding it like:

"3/16
"1-1/16
"3-1/8
.xx cid
15.7oz
1oz to a US pint

LOL, I ordered an engine from Tower and included some mounting hardware, I picked some bolts on random that looked OK in the picture, they were "4-40" and I thought, "Yeah, whatever!"
Got the engine and the bolts, the bolts were verry small :)



Hobbsy -> RE: metric is easier!!! (11/5/2004 1:09:03 PM)

This is one Amuurakin who likes and uses the metric system, I can identify an M4 bolt as easily as a 6-32. Occasionally the thread pitch gets me, my wife is a Pharmacy Technician so both of us find it easy.

adamkerrnz,

How soon do you want that 1/4-32 glow plug thread to change?

What's the thread size for the spark plugs in your car?

Treads in car plug are M14x1.25 [:D]

Metric glowplug treads will be M6.3x0.85, it will be same as "1/4-32. [;)]

Mr_Ed -> RE: metric is easier!!! (12/2/2004 9:15:53 PM)

Actually, you don't have to go to metric to keep it simple. Just use ounces instead of percent when you measure the ingredients. For instance: when mixing fuel with 20% oil, and 10% nitro, use 20 ounces oil, 10 ounces nitro and the rest (70% or 70 ounces) alcohol. You end up with less than one gallon (100 ounces vs. 128 ounces). But it sure makes things a lot easier than trying to measure 1/4 ounce or .68 ounce.

Try it.

Hircflyer -> RE: metric is easier!!! (12/2/2004 9:30:20 PM)

I have to admit M6.3x0.85 is certainly easier to understand than 1/4x32, sure it is..........about as easy as women are to understand.



Rupurt -> RE: metric is easier!!! (12/3/2004 5:17:40 PM)

maybe when you get your head around 24 hour time the metric system will come easily[:D]



Hircflyer -> RE: metric is easier!!! (12/3/2004 6:43:22 PM)

I spent 23 years in the USAF I understand 24 hour time, ZULU Time, GMT, and anyother way to tell time. What I don't understand is how M6.3x0.85 relates to 1/4x32.

Sorry it doesn't compute.



Rupurt -> RE: metric is easier!!! (12/3/2004 7:47:13 PM)

Ok just kidding, if you are serious
6.3mm = 1/4inch
32 is thread per inch (as far as i know)
0.85 is the distance between the top of each thread



Jim Thomerson -> RE: metric is easier!!! (12/3/2004 8:15:08 PM)

Why doesn't a metric minute have 100 seconds and a metric hour 100 minutes?[8|]

Jim



Rupurt -> RE: metric is easier!!! (12/3/2004 8:27:56 PM)

Hey this topic is almost as hot as castor vs synthetic

seconds are divided by tenths, hundredths and even thousandths



Hircflyer -> RE: metric is easier!!! (12/3/2004 8:30:52 PM)

Ok I'm starting to get it........ .85 is what? is that same as threads per inch? so it would be .85 per MM ? I don't get how the .85 tells me how many threads per MM or don't I care? do you just look for a .85 nut?

so far the 6.3 MM equaling 1/4" is the only part I understand. But I still say its easier to find a 1/4" wrench than it is to find one marked 6.3

And don't start on centimeters!



Hircflyer -> RE: metric is easier!!! (12/3/2004 8:34:00 PM)

At least I understand the difference between castor and synthetic. One comes from a bean the other doesn't! ha



Rupurt -> RE: metric is easier!!! (12/3/2004 8:41:20 PM)

Alright the 32 in this case is how many threads there are in an inch. The metric system refers to the space between each thread So the 0.85 is actually 0.85mm between threads.



Rupurt -> RE: metric is easier!!! (12/3/2004 8:47:23 PM)

Oh and we dont have spanners with 6.3mm as far as i know it would probably be called a quarter inch, the popular ones are 5,5mm and 7mm



c550 -> RE: metric is easier!!! (12/16/2004 7:24:35 PM)

Off topic a little, but a chance to vent. The metric system is a disaster as far as full scale aviation is concerned. Engine limits in bar. instead of psi ect. Nautical miles are easy to measure and calculate; I.E. one nautical mile=1/60th of a degree of latitude. A meter doesn't equal anything. Sorry for the rant, but I'm stuck flying a french helicopter.

Regards,

Dave
