How to convert Watts to Amps?
You cannot convert watts to amps, since watts are power and amps are coulombs per second If you have at least least two of the following three: amps, volts and watts then the missing one can be calculated. Since watts are amps multiplied by volts, there is a simple relationship between them.
However, In some engineering disciplines the volts are more or less fixed, for example in house wiring, automotive wiring, or telephone wiring. In these limited fields they often have charts that relate amps to watts and this has confused people. What these charts should be titled is "conversion of amps to watts at a fixed voltage of 110 volts" or "conversion of watts to amps at 13.8 volts," etc.
The Following Equations can be used to convert beween amps, volts, and watts.
Converting Watts to Amps
The conversion of Watts to Amps is governed by the equation Amps = Watts/Volts
For example 12 watts/12 volts = 1 amp
Converting Amps to Watts
The conversion of Amps to Watts is governed by the equation Watts = Amps x Volts
For example 1 amp * 110 volts = 110 watts
Converting Watts to Volts
The conversion of Watts to Volts is governed by the equation Volts = Watts/Amps
For example 100 watts/10 amps = 10 volts
Converting Volts to Watts
The conversion of Volts to Watts is governed by the equation Watts = Amps x Volts
For example 1.5 amps * 12 volts = 18 watts
Converting Volts to Amps at fixed wattage
The conversion of Volts to Amps is governed by the equations Amps = Watts/Volts
For example 120 watts/110 volts = 1.09 amps
Converting Amps to Volts at fixed wattage
The conversion of Amps to Volts is governed by the equation Volts = Watts/Amps
For Example, 48 watts / 12 Amps = 4 Volts"

The Defenders Organisation is trying to get everyone who is interested in ecology, birds, wildlife, and forests in general to sign a petition online - very easy to do.
The following is a quote from an email they sent out... "One of the world’s largest intact forest ecosystems -- the breeding grounds for many of the world’s warblers, ducks and other migratory birds -- is in big trouble.
Oil and gas, timber, mining, and other industries are destroying vital habitat for birds and other wildlife in Canada’s boreal forest. We need your help to stop them."

Bloggers unite for Human Rights.
There are many great human rights organizations all over the world, but if you want to know something about Amnesty International, please visit AmnestyUSA for more information
Some of the source material provided by Amnesty for BlogCatalog can be found here... Unite-Blogcatalog - you can, obviously, write on whatever rights topic you choose, but you will nevertheless find some interesting and thought provoking material on this page.
Please think of Shi Tao and press the Chinese government to release him and others who were jailed simply for their legitimate use of the Internet. Human rights in China have been in the news, especially with the Olympic torch and Olympics this summer. Now the people of China are suffering from the earthquake and its after-effects and the destruction. Their rulers are making a better job of trying to rescue their citizens than can be said for thosse in Burma.
Our thoughts will be with all the victims.

Further advice on battery storage
The following is some really useful information which I received in an email from all-battery.com (USA)
You'll find their advice within the quotes...
"Alkaline batteries stored at "room temperature" self discharge at a rate of less than two percent per year. So normally refrigerating or freezing them will only help maintain their charge by a tiny amount. Hardly worth the effort of chilling them. However, if alkaline batteries are stored at higher temperatures they will start to lose capacity much quicker. At 85 degrees F they only lose about 5% per year, but at 100 degrees they lose 25% per year. So if you live in a very hot climate or are storing your batteries in a very hot location, it may be worthwhile for you to store your alkaline batteries in a refrigerator instead.
NiMH and NiCd batteries self discharge at a MUCH faster rate than alkaline batteries. In fact, at "room temperature" (about 70 degrees F) NiMH and NiCD batteries will self discharge a few percent PER DAY. Storing them at lower temperatures will slow their self discharge rate dramatically. NiMH batteries stored at freezing will retain over 90% of their charge for full month. So it might make sense to store them in a freezer. If you do, it's best to bring them back to room temperature before using them. Even if you don't freeze your NiMH batteries after charging them, you should store them in a cool place to minimize their self discharge."
