While you can't exactly compare the two, the equivalent voltages, currents and powers can worked using the idea of RMS (which is the equivalent value in AC); this is the value which is given for just about everything you plug in: microwaves, toasters, shavers... Just calculate "DC x square root of half = equivalent value of AC". The opposite is "AC x square root of two = DC". For example, 240 Volts (normal home voltage) AC x sqrt 2 = about 340 Volts DC or 6mA DC (the amount needed to stop a human heart) x sqrt 0.5 = 4.2 mA AC.

∙ 12y agodc watts = ac watts Watts are a measure of power or heat. 5V DC @ 1 A = 5W, same with AC 5VAC @ 1A = 5W
As for inverter conversion losses, they vary widely from 60% to 95%, somewhat tracking price, higher price = higher efficiency. (not counting ebay inverter scams)

Is Singapore's power grid AC or DC?
AC
How does an ac power source differ from a dc power source?
AC power sources are the adapter power sources. DC power sources are the direct power sources. DC stands for direct current, meaning it is a direct source of energy., and AC stands for alternating current, which means it is a secondary source of power.
What component converts AC into clean DC power?
By using rectification we can convert the AC into DC....
Does a computer use AC or dc power?
Both, in a way. Electronic components, including moth components inside the computer, need DC. However, since the power available in homes or offices is AC, a computer is designed to work with this. A computer has a power supply that internally converts AC to DC.
Is ac or dc power cheaper to produce?
To produce it and distribute it, ac is much easier.
What IS AC power and DC power?
AC Power is Alternating Current whereas DC Power is Direct Current.
Is car power AC or DC?
DC
Are TV's in buses AC or DC input?
Televisions in buses can be either AC or DC current. It depends on whether the bus is using a DC to AC power convertor or an AC generator or DC power from the battery.
What is main difference between ac power and dc power?
AC power is made by alternating current and DC does not change.
What is a DC AC inverter used for?
A DC/AC power inverter is used to convert DC, the power that comes from a car's battery, into AC, the kind of power that is supplied to a home and used to power larger electronics.
Can you plug an AC computer into a DC plug?
You can plug an AC computer into a DC plug only if you also have an inverter to transform the DC power into the AC power that the computer power supply expects.
Do laptop work on ac or DC and how?
A laptop runs on DC. Either from the battery, or the external power supply, which converts AC power to DC.
Is Ethernet voltage AC or DC?
It's AC. DC power is constant, and therefore cannot carry any sort of signalling along with it. Don't think that AC power inside ethernet cables can be used as is, since it depends on what kind of data in being sent across.
Is Singapore's power grid AC or DC?
AC
How does an ac power source differ from a dc power source?
AC power sources are the adapter power sources. DC power sources are the direct power sources. DC stands for direct current, meaning it is a direct source of energy., and AC stands for alternating current, which means it is a secondary source of power.
Why ac is more effective than DC?
because power dissipated in ac is less than power dissipated in dc.
Does a car run on AC or DC?
The power supply in most cars is DC. The alternator may produce AC power, but it is then run through a rectifier, providing DC power.
