Mindscrape, I reaaaaaaaaaaaaally appreciate the above answer and explanation. 4.448 x 3.3 = 14.6784... which is the first answer before all that other stuff to get you back to that figure. Anyway, I am going to keep reading this till it sinks in. I don't quite get it yet. But then I am...

Is this simplification of the definition of the ampere fair? The amp is the current that produces a pressure of 2 micropascals. Thus, given 1 micropascal is equal to c. 0.020885 micro pounds-force per square foot, or c.1/47.88 micro pounds-force per square foot, then if we define the...

Really I'm just trying to grasp the thing in solid terms. Converting to another system - this hypothetical foot-pound electrical system - helps me make it more understandable in my mind. :)As I say, I understand how to express the definition of the ampere in foot-pound units. However, if we have...

Hmm, I tried figuring it out another way and am completely confused now. Heh. If 1 "NECU" is "that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 foot apart in vacuum, would produce between these...

No one...? heh :( :P :)

Y'see, I'm trying to figure out how a system analogous to SI, but based on foot-pound units, would work (in case anyone's interested). Yes, I know, silly and pointless, but still... I'm curious :)The amp is defined as "that constant current which, if maintained in two straight parallel...

okay... Ah right. Yes indeed. Hah! It's so obvious. Sorry, I studied Linguistics and Language; maths and physics aren't my strong points :D Thank you very much. :D :D :D(So, 1/683 Watt = around 1/926.0238ft-lb/s)

bump? No one fancy answering? :)

I don't see the problem. Slug has to do with slugging someone (as it were), or old slugs in cannons; nothing to do with slimy animals! :D A way to get rid of this small, slimy creature notion might be to think of slugging someone; would you slug them if you hit them with a slug = animal, or...

I didn't realize at the time! I was just looking thru threads and had something to add!

Nej. The poundal (pdl) is the unit of force when m = pound and a = ft/s/s. It is around 1/32.17405lbf The slug is a unit of mass when the unit of force is the pound-force instead of the poundal (and when the unit of length is the foot). This, then, is equal to around 32.17405lbm.

Hi guys, I need some help converting between units. I hope you can help. :) The candela is defined as "the luminous intensity of a light source producing single-frequency light at a frequency of 540 terahertz (THz) with a power of 1/683 watt per steradian". Now, one watt is equal to...

This is a fair point. Part of the issue here seems to me to be about the possibility that any benefits would be illusory and not real.

Warren's world philosophy- It is not possible for a member of an organisation- political or otherwise- to hold slightly different views to those expressed in the organisation's manifesto. Actually, the DSGB beleives dozenal should replace decimal EVENTUALLY, and in the mean time wishes to...

You are really naive, you know that. Laws passed in the nineteenth century outlawing customary systems of measurement and replacing them with metric of course still have relevance to-day. Look: These customary systems were outlawed and abolished, and all standards switched to metric. It is...
