Conversion factor from amperes to milliamperes

In summary, the conversion factor from amperes to milliamperes is 10^-3 or 1/1000. This means that to convert from amperes to milliamperes, you would multiply the value in amperes by 1000. For example, 3.5 amperes would be equal to 3.5 * 1000 = 3500 milliamperes. Remember to move the decimal point to the right when converting from amperes to milliamperes and to the left when converting from milliamperes to amperes.

can anyone tell me the conversion factor from amperes to milliamperes?
I know that milli is 10^-3 but i don't understand how it would look. like for example, 3.5 amperes is how many milliamperes? is it that 3.5 x 10^-3 = 0.0035 amperes?

1 Ampere = 103 mA (milliamperes)
3.5 A = 3.5 * 103 mA

It is similar to
1 m = 103mm = 1000 mm

It is three thousand five hundred milliamperes.

so its 3.5 divide 10^-3 in other words?

Incorrect, you wouldn't divide but instead multiply. Otherwise you would get 3,500 amps.

Hmm... let's try to de-confuse here.

You state, very correctly that 1 A = 1000 mA = 1*10^3 mA

Now, divide that by 1000...

1*10^-3 A = 1 mA

This is your conversion factor.

Let's multiply the first equation by 3.5...

3.5 A = 3500 mA = 3.5 * 10^3 mA

There you go...

heres how I remember...
think of a line eg. -3, -2, -1, 0 ,1,2,3. get my picture?
anyways see what direction negative goes left, right?
see what direction positive goes to the right, do you see?

here the magic...
pretend your number 3.5 is on the zero line.
and the 10^-3, the -3 is telling you what direction to go to the left, got it!
Dx :wink:

so many technical explanations.

when it is 10 to the power of somthing, just move the decimal place that many places and you will get the original value

100 mA = 100.00
m = milli = 10^-3
so by moving the decimal place 3 places left you get
.1A which equals 100mA

you do the same to reverse it .1A to mA is done by moving the decimal place 3 places to the right

try and remember this:

10^18 = exa = E
10^15 = peta = P
10^12 = tera = T
10^9 = giga = G
10^6 = mega = M
10^3 = kilo = k
10^-3 = milli = m
10^-6 = micro = ...cant find symbol but its similar to u
10^-9 = nano = n
10^-12 = pico = p
10^-15 = femto = f
10^-18 = atto = a

once you get used to doing it it becomes easy
 

1. What is the conversion factor from amperes to milliamperes?

The conversion factor from amperes (A) to milliamperes (mA) is 1,000. This means that 1 ampere is equal to 1,000 milliamperes.

2. How do I convert amperes to milliamperes?

To convert amperes to milliamperes, simply multiply the value in amperes by 1,000. For example, if you have 2 amperes, the conversion would be 2 x 1,000 = 2,000 milliamperes.

3. Why is it necessary to convert from amperes to milliamperes?

In some cases, it may be more convenient or accurate to use milliamperes instead of amperes. For example, in electronics, the currents are often measured in milliamperes instead of amperes because they are smaller values.

4. Can I convert from milliamperes to amperes?

Yes, you can convert from milliamperes to amperes by dividing the value in milliamperes by 1,000. For example, if you have 5,000 milliamperes, the conversion would be 5,000 ÷ 1,000 = 5 amperes.

5. Is the conversion factor from amperes to milliamperes always 1,000?

Yes, the conversion factor from amperes to milliamperes is always 1,000. This is a fixed ratio and does not change regardless of the value being converted.
