Voltage is a property of electrical potential. Amperes (and miliamperes) are the units of electrical current. Even though these are related to each other in a circuit, they are not the same thing, and they cannot be "converted" into each other.
Also, these properties are only related through a "load" the circuit provides (the resistance and inductance of the circuit), and make sense only when related to each other this way. If there is current, there will be voltage as well, but if there's only voltage, there will be no current unless there is some resistance as well (even a wire has resistance) - otherwise the circuit is "open" and no charge is flowing.
In a simple circuit with a voltage source and resistor:
milliamps = voltage*1000/resistance.
If your circuit has diodes, capacitors, inductors, etc. it gets much more complicated.

How do you convert Mega Joules to Joules?
You can't convert them directly, because they measure different things. The unit for energy is the Joule. Power means how fast energy is transferred; it is measured in Joules/second, also called Watts.
How many amps to a kilowatt?
That depends on the voltage.
How much current in amps flows through a circuit with a 100 resistance?
You don't have enough information in your question, you need to include the voltage as well. One relevant equation is V = I * R where V: Voltage, I: Amps, and R: Resistance. When you have the voltage divide the Ohm resistance into that and you'll get your amps.
What is the three uses for energy?
the three uses of energy are voltage, amps, and resistanc
How many watts in a curling iron?
The current draw in amps mulitiplied by the voltage.
Convert 1000 ohms to amps?
Can not do it without knowing the voltage I = E/R. Amps = Voltage/Ohms.
Convert 38milliamps to amps?
Milli = 1/1000. This is all the info that you should need.
37.5 amps converted in watts?
To convert amps into watts a voltage is needed. Watts = Amps x Volts.
40 milli amps per minute for a total of ten minutes?
400 milli amps total.
What is 0.011 in converting watts to amperes?
To convert watts to amps a voltage value must be given. Amps = Watts/Volts. Amps = .011/Volts.
What is 3.50 amps milli-amps?
3500 mA
How many amps are a watt?
No.By which I mean: amps and watts are not just different units, they're different TYPES of units. You can't convert amps to watts without knowing the voltage (if you DO know the voltage, multiply volts by amps to get watts).
How do you convert 5kw and 120 voltage to amps?
5000w / 120 volts = 41.66 amps P=E*I transposed to I=P/E
How do you convert DC voltage to watts?
You would also need to know the current in amps. The formula you need is this: P = I V Power (in watts) = current (in amps) x voltage (in volts)
1 ampere is how many milliamperes?
Milli means a 1000Th of a unit. It is convenient since 1 micro amp if written becomes 0.000001 amps and 1 Milli amps becomes 0.001 So, to convert milliamperes to amperes, you divide by 1000.
700 milli amps 9 volts?
Power P = amperage I times voltage V. The power is 0.7 times 9 = 6,3 watts.
How many amps are in 20 ma?
ma stands for milliamp. The prefix 'milli is equivalent to .001 So 1 amp would be 1000 milliamps and 20 milliamps would be .02 amps
