| ||1000s pF
| |10000s pF
| 100000s pF
1,000000s pF


That'd be 500 pF in your case. Multiply the value in uF by one million to calculate the value in pF.

It would also have been listed as 500 mmf before the US was forced to switch to kiss European butts.

Move the decimal point 6 places to go between mf and pf.

Milli, micro, nano, pico (or m, u, n, p) - it's all perfectly straightforward, 3 orders of magnitude at a time, I don't see what the big deal is.

Those old schematics where "M" means two different things on the same drawing and you have to stop, think and use some common sense, OTOH... :wink:

Most of the newer TV and home entertainment schematics (Especially Philips) use NF designators now.

It´s not so difficult.
The only problem is that people confuse capital ¨M¨ with ¨m¨
Thanks to Napoleon whole Europa has (except Gr.Britain) the decimal system.

I found this list on the Internet with a little help to remember:

Every Exta 10*18
Person Peta 10*15
That Tera 10*12
Gave Giga 10*9
Me Mega 10*6
Kisses Kilo 10*3
Has Hecto 10*2
Diarea Deca 10*1

diary deci 10*-1
cows centi 10*-2
make milli 10*-3
milk micro 10*-6
not nano 10*-9
pink pico 10*-12
fruit femto 10*-15
a*hole atto 10*-18

Who forced the US to kiss Euro arses?

Australia went down the same path 40 or so years ago, ostensibly because of their ( now tenous) ties with the UK and Europe, but what would have forced you guys to follow suit?

The bloody socialist academics and pseudo intellectuals at IEEE. There was a huge battle where I worked when the switch was made. At least we still have mph and real road signs :D

OTOH, the US adopted a decimal currency while the UK still used Pounds, Shillings and Pence (2 Farthings to a Ha'apenny, 4 Farthings or 2 Ha'apennies to a Penny, 3D to a Thruppenny Bit, 6D to a Sixpence or Tanner, 2 Tanners or 12D to a Shilling or Bob, 2 Bob to a Florin, 20 Shillings to a Pound, etc).

Don't you believe it! We have a decimal system in place and have since the early 70's. Many of us of a certain age however, still use imperial, even if it is somewhat different to yours. Examle, a gallon is 8 pints here, only 6 in the US

Its usually the other way around - the USA defining the use of the English language.

We spell it "colour", you spell it without the u.
We say "zed" not "zee" - do you guys have any idea how annoying it is to hear out schoolkids saying ex why and zee?

I tell ya, tis a good job we're allies!

BTW, I AM only teasing you guys ;)

Not according to wiki

The imperial gallon

The imperial (UK) gallon, defined as 4.54609 L, is used in some Commonwealth countries and was originally based on the volume of 10 pounds of water at 62 °F (17 °C). (A US liquid gallon of water weighs about 8.33 pounds at the same temperature.) The imperial fluid ounce is defined as 1⁄160 of an imperial gallon.

The US liquid gallon

This gallon is defined as 231 cubic inches,[2] and is equal to exactly 3.785411784 litres or about 0.13368 cubic feet. This is the most common definition of a gallon in the United States. The US fluid ounce is defined as 1⁄128 of a US liquid gallon.

Norm is right that there are 8 US pints in a US gallon, but a US pint is smaller than an Imperial pint.

Plug 1 us pint in imperial pints into Google and you get "1 US pint = 0.83267384 Imperial pints" (so a US gallon is about 6.6 Imperial pints).

We're not all socialists; maybe pseudo intellectuals. I don't recall the IEEE ever being able to force anyone to do anything. Lots of discussion and debating, but decisions got made by the companies who elected to change their spec systems. I think it 's the influence of international trade, rather than an intellectual conspiracy. I didn't want to give up on "kcs." !
