No need to apologize I should have referenced the year. I've been at this for 3 or 4 years and forget that some of my references are before other people got started with this.
By the way Mario your English is better than a lot of people that live here, for whom English is supposed to be their first language.
Your electric bill is charged by Kilo Watt Hours. A watt minute is just a smaller amount of energy. A watt is a measurement of power and a watt minute is the amount. Here is my formula for the 55 watt minutes / litter.
Amps = 4A
Volts = 13.7V
Watts = 4 *13.7 = 54.8W
Minutes per litter = 1MPL
Watt minutes per litter = 1MPL * 54.8 = 54.8 WM/L
1 Min * 54.8 W
---------------- = 54.8WM/L
1 Litter
The next measurement
11Amp * 13.7V = 150.7W
Minutes per litter = 0.93MPL This equalls 1.07 LPM
Watt Minutes / Litter = 0.93 * 150.7W = 141 WM/L
0.93 Min .* 150.7 W
---------------- = 141 WM/L
1 Litter
If you state that you used 150.7 Watts and created 1.07 LPM then you would divide 150.7 by 1.07 litters. The "time" it took is being left out and it’s no big deal because we all know what we are talking about. But I feel that the most accurate way to state the results is in Watt Minutes. It quantifies the amount of power.
As for the 1 LPM at 4 amps, I made a typo. It's 0.5 LPM. I think I had the number of amps in my head when I wrote that figure. Thank you for calling me on it.
Here is the math:
4Amp * 13.7V = 54.8W
Minutes per litter = 2 MPL
Watt Minutes / Litter = 2 * 54.8W = 109.6 WM/L
2 Min .* 54.8 W 109.6 WM
---------------- = -----------
1 Litter 1 Litter

Ok, I have now hit my ceiling. If 12V @ 1Amp is 12 watts. What is the amount of time that it takes to use the 12watts? Is it measured in seconds, minutes, hours? How long does it take for a 100watt light bulb to use 100 watts of power?

If I understand correctly, it takes 1 hour for a 100 watt light bulb to use 100 watts. Is this correct?

ops, i was wrong !

It takes 1 second for a 100 Watt bulb to "use" 100 Watt-seconds of power.
That is why a 100 Watt bulb burns brighter than a 60 Watt bulb.
The bulb is running AT 100 Watts from the moment of turn on.
If it ran for 10 hours, it would consume a Kilo-Watt Hour of power.
