mA and Writing

Am I right that 5 mA I would write it out as 0.005
And 8 mA I would Write it out as 0.008

But when you get to 10 mA do you Write it as 0.010

Thanks for the help

Yes, but for completeness it should be 0.005 A and 0.010 A where A stands for amperes.

m stands for milli which is 1/1000 so you move the decimal point three places to the left when going from mA to A, as you have done.

0.01A = 10mA = 10,000uA = 0.00001kA = ...

Are you asking about why there is a trailing "0" on "0.010A" for 10mA instead of "0.01A"?

The 0.010 is more precise than 0.01 mathematically. It easy to use engineering notation like milli (-3), micro (-6), mano (-9) pico (-12), so 10 mA becomes 10E-3 Amps

There is a difference between 10, 10.0, 10.00 and 10.000000000 mA. Also don;t write numbers without the leading zero. e.g. write 0.1 and not .1

You can throw a book at "accuracy", "precision" and "repeatability" and there are rules to follow.

mV/k ohms is in units of Amps, but watch 100 mV/1000 ohms.
