I checked on the site for a conversion of Watts to Amperes but could not find it. Could someone please help with that?
Thanks.

How do I convert Watts to Amperes
Forum rules
Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

There is no conversion from Watts to Amperes.
A Watt is a unit of power (Work), An Ampere is a unit of measure of the rate of electron flow or current in an electrical conductor.
There is, however, a formula: Wattage is equal to the voltage (A unit of force) multiplied by the current.
- Code: Select all
W = VA
So: In order to convert Watts to Amperes:
- Code: Select all
W = VA
- Code: Select all
W = VA
- --
V V
- Code: Select all
W
- = A
V
You will need to divide the Wattage by the voltage.

Converting watts to amperes
by Jens » Sat Dec 31, 2005 4:32 am
The standard formula for calculating power (in watts) is easy as pie (a mental hook). The formula is
P = I E
where
P is the power in watts
I is the current in Amperes (not VA!)
E is the RMS voltage for AC (typically 115V from the wall socket)
If you are calculating using DC voltages, then you use the absolute voltage. ie: -12V dc use 12V since negative power does not make sense for what you are doing.
good luck
