Changing over from amp-hours to watts or the other way around isn’t as basic a procedure as you would might suspect, since they measure various things. Amp-hours measure a measure of flow, while watt-hours are a proportion of electrical force. Be that as it may, you should simply change over watts to watt-hours, and afterward you can utilize a straightforward condition to change over watt-hours to amp-hours. Prior to finishing the figuring, you have to comprehend what the terms mean and discover the voltage of the battery.
Amp-Hours and Watts Defined
An amp-hour (Ah) discloses to you the measure of current a battery can give over a specific measure of time, and a rating (as a rule in amp-hours or milliamp-hours) is utilized to give you a thought of to what extent a battery can give a given measure of current. Amp-hours are determined by duplicating the quantity of amps (An) a battery gives by the release time in hours (h). Along these lines, if a battery gives 10 amps of current to 10 hours, it is a 10 amps × 10 hours = 100 Ah battery.
A watt (W) is a proportion of intensity, with 1 watt speaking to one joule (a unit of vitality) every second. In this way, if a light uses 60 watts, it requires 60 joules of vitality for each second. In a manner like amp-hours, a watt-hour (Wh) is the measure of vitality utilized when something works at a given number of watts for a specific number of hours. This implies 1 Wh is the measure of vitality utilized by something working at 1 W for 60 minutes, and 60 Wh is the measure of vitality something would utilize working at 60 watts for 60 minutes.
Changing over Wh to Watts and Back
Before you can do the principle transformation, you have to change over the quantity of watts your hardware works at to a sum in Wh. This is simple: Multiply the measure of watts something works at by the quantity of hours it works for. For instance, a 60-watt bulb running for three hours approaches 60 W × 3 h = 180 Wh.
You can generally change over back to W from Wh by partitioning the sum in Wh by the quantity of hours the gadget was running.
Amp-Hours to Watts Equation
There isn’t a condition for amp-hours to watts straightforwardly, however with watt-hours, you can utilize the basic connection:
Amp-hours × Volts = Watt-hours
In this way, to get amp-hours from watt-hours, you use:
Watt-hours ÷ Volts = Amp-hours
This implies you have to discover the voltage as recorded on the battery to finish the estimation. The voltage is constantly recorded on the battery or in its determinations some place, or potentially in the manual for the gadget on the off chance that you have one.
Amp-Hours to Watts Conversion
Utilizing the case of the 60-watt light laboring for three hours from previously (180 Wh) and accepting the utilization of a 12-volt battery, the change can be finished.
Partition the measure of watt-hours by the quantity of volts to change over: 180 Wh ÷ 12 V = 15 Ah. This is what might be compared to 15 amps of current running for 60 minutes, or – as right now 5 amps of current for three hours.
