Usa Wpg Not Uk?

[Valmyre]

In order to calculate ones WPG do you have to calculate it using USA Gallons? Seems strange not to use UK measurements. But doesn't the USA have a different volt/amp measurment to th UK?

Thats because UK gallon is only used in UK . Over here in canada we still use US gallon as our tank measure and many other stuff. And I think many more place use US gallon as there measure for many thing. So thats probably why they use US gallon per wt rules instead of UK.

Okie thanks , but isn't the USA watt/amp/volt system differnet to the UK's ?, and if it is the calculation fo wpg would not be correct.

Nope. Watts, amps, and volts are universal.

 

[Valmyre]

okie thanks , well thats cleared that up

The USA runs on 110v, with a higher amp rating. But in terms of watts, we all use the same. A 10W light uses 10W wherever it is plugged in.

1 Watt = 1 Ampere x 1 Volt

(I hope I'm right)

 

[piper]

Yes you are, Q = I*V

 

[andywg]

But surely I=V/R

Therefore:

If you use a device rated for the UK in America it will draw only half the power...

230W in the uk = 1A, or 1 Ohm

Put that 1 Ohm against the US voltage of 110V and you will get 110W.

N'est pas?

This thread is reminding me of my current AS level physics course .

Actually Canada does use Imperial gallons for many things that aren't metric. Gas is sold in Imperial gallons. To be honest I didn't know aquariums were being sold using US gallons, I've never bought a new one. )

Hmmm... So UK uses 230V? If that's the case, you're right. But you'll never see a 230V equipment here. I'm pretty sure you won't see 110V equipments there either. When the manufacturer specifies X watts, it's respect to the standard voltage found in that particular region. If you plug in US 110V equipment into UK 230V outlet (if that's even possible), you may find stuff catching fire.

I sometimes wished everyone would use the standard MKS units. Less stuff to get mixed up/confused/memorize...

It's not possible, the plugs are completely different shapes... they do make converters that change over both the voltage and the plug shape, though. Very handy for traveling with electrical appliances

I had an old adapter which I used for my keyboard (for music, not the computer keyboard). I had accidently set the voltage on the adapter to 110V and sure enough, there was smoke

Since we are already a bit off topic, I have another question. I bought a 36 watt cool-daylight fluorescent bulb yesterday for my tank, the thing is, that bulb can light my my whole room...Do you guys have SO MUCH LIGHT for the tank ??

PS: I already have a 20watt tube in my tank, and the 36 watt will increase the lighting to 2.43 wpg
