Ampere-hours is a battery hold-up time rating. Volts is a voltage rating. The two are not related, so the question cannot be answered as asked.
You can not convert Watts (Power) to Ampere-Hours (Amount of charge)!!! Exept if you know the voltage and the amount of time you use the power. For example: If you use P=216 W from a battery of V=12 Volts for t=1 hour, that would be: Current I=P/V=216/12=18 Amperes In time of 1 hour, you will take Q=I*t=18 Ampere-Hours from the 12 Volts battery.
That's like asking how many meters in a liter. Ampere and Volt are two DIFFERENT measurements. Ampere is how much electricity you are using, while volts are how much pressure the electricity is under(Think water). If you want to figure out how many amperes your appliance is using you could use this formula: P=UxI (Watt=Volt x Ampere) or U=RxI(Volt=Resistance x Ampere).
k is 1000 V is volts A is amps basic algebra kVA = (V * A)/1000 120 Volt with 20 Amp would be: (120 * 20)/1000 = 2.4 kVA
Since the equation for watts is: Volts * Amps = Watts that would mean 12 Volts * 1 Amp = 12 Watts
ohm is used to measure resistance of electric current. Ampere is used to measure electric current. volt is used to measure voltage.
Yes, ampere will go down.
Yes, that is safe.
To find our what charging ampere to use a simple way is to divide the battery Ampere with its ampere hour (i.e. for car batteries they will say 75ah C/20) this means that the battery has 75 ampere rating based on 20 hour rating... as such to find the charging ampere divide 75 by 20 to get a charging ampere of 3.75... this is for a slow charge - to speed up the charge divide the ampere by 5 hours (to charge the battery from empty to full in 5 hours)...
.63 ampere draw @ 7 volts
The number of Ah (ampere-hours) or milli-ampere-hours tells you NOTHING about the voltage. It is the amount of current (amperes), multiplied by the time such a current can be extracted from the battery.If you multiply the number of Ah by the voltage, you will get the energy stored in the battery.
30 amps.

It's (part of) the specification for a battery. The battery holds a nominal 12 Volts and has a capacity of 100 ampere-hours. Means it can supply a drain of 1 ampere for 100 hours, 2 amps for 50 hours etc etc Before the voltage has dropped enough to make the battery useless.
Volts; The Ampere is the unit for current in charge per second.
one and a half volts in a C battery.
Assuming this could be done with no conversion loss a 20 watt load at 120 volts would require about 1/6 of an amp. A 7 ampere hour battery would run the load for 6 x 7 = 42 hours. However, if you actually built a circuit to up convert 12 volts DC to 120 volts AC there would be significant conversion losses.
The problem here is that "Ah" (ampere-hours) is not a unit of energy. To convert that to units of energy, you need to multiply by the voltage of the battery. The result, of course, will vary depending on the battery type.The result of this multiplication would give you ampere-hours-volts, or watts-hours (watts times hours). Therefore, you can then divide by the number of watts used, to obtain the time (in hours).
