Souper man said:what is a 100nf cap? isnt it like 1uf? I never use nano in my cap measurements.
just pico,micro, and farad. some pretty big jumps, but works.
I hate the american measurement standards. I wish they taught everybody the metric system,which is so much easier. I self taught myself metric, because imperal sux

Well it's very common.Souper man said:what is a 100nf cap? isnt it like 1uf? I never use nano in my cap measurements.
Remember, it's every power of three it jumps to a new name.just pico,micro, and farad. some pretty big jumps, but works.
I agree but nano is a metric quanitiy.I hate the american measurement standards. I wish they taught everybody the metric system,which is so much easier. I self taught myself metric, because imperal sux

jpanhalt said:That question has not been answered per se: 100nF is 0.1 uF (microfarad).
As for metric vs. the imperial/American system. I use both and like both, but for different purposes. There is nothing wrong with dividing an inch into tenths, hundreths, thousandths, etc. NB: Something machined to 0.001 (typically the smallest graduation on a dial) is more precise than something machined to 0.05 mm (also a typical smallest division on a dial). Sure, one can divide the dial into 0.025 mm units, but it is also easier to count in "thousanths" than it is in "0.025 mm" intervals. Consider the problems people have in multiplying by 1000in their heads.
That leaves one to argue about whether the inch or the centimeter is a more "logical" unit. I like the anthropomorphic reality of an inch. A size 32 in. sleeve has real meaning and 81.5 cm is too big a number to visualize
As for taking fractions of various dimensions, including time, I prefer numbers that have more factors. That is, 36, 12, 16, etc. are easier to deal with than 100 and 10. Just how do the metric countries measure a third of a meter anyway? John
dknguyen said:Although I understand the convenience of using multiples of 12, 16, and 36 when counting on your fingers, most technical things don't seem to have such luxuries in which case it seems to make everything harder.
dknquyen said:It's also silly when you consider that there is no imperial equivelant to measure things like capacitance, resistance, magnetic fields, etc.
jpanhalt said:How so? BTW, most people have only 10 fingers.
Binary also seems to work better than base 10 for computers. A lot of coding systems work on hex. Some people confuse anything that is decimal with metric. Metric refers to a specific system. Its usage is not as standardized throughout the world, as some might think.
Do you really mean "silly." The American system simply incorporates those units in it. Just like our language can assimilate words from other languages. There's nothing silly about that. In fact, it makes perfectly good sense.

Most of the world uses the decimal system for wieghts measures and even currency.Metric refers to a specific system. Its usage is not as standardized throughout the world, as some might think.
Form whatever opinion you will but I feel that the decimal system is just easier to use mainly because it's consistant; It always uses base 10. Imperial is inconsistant, for example there are 12 inches in a foot and three feet in a yard and this only makes calculations harder as you need to mess around with remainders and fractions.Do you really mean "silly."

Bob Scott said:Souper, don't get US mixed up with Imperial. The American SAE system is different from Imperial.
A US gallon (128 US Oz) is 3.78 Litres
An Imerial gallon (160 Imperial Oz) is 4.5 Litres.
A US pint is 16 Oz.
An Imperial pint is 20 Oz.
And the volume ounces are different too. US Oz. are bigger.
Force/mass conversions can be confusing. In metric, KG can be used for weight and mass. The unit of force is the Newton. In Imperial, Pounds can be used for weight and force. The unit of mass is the Slug.
Do the British still use wrenches that are uniquely British size?
I'm also curious..Do you still need to buy licenses to own televisions and radios in England?
