Question

How do i convert 478mg into kg using a TI 84+ graphing calculator?

Answer 1

that kind of calculation is meant to be done mentally and im not going to do your homeowork for you

Answer 2

You can do it without a calculator, but it is simple.

478mg x (1g/1000mg) x (1kg/1000g)= .000478kg

Answer 3

Go into APPS

Click on SciTools, way at the bottom

Go to C for SI Prefixes (Mass won't work b/c there is no kilogram)

Type in your number and click m (small m)

Click k and your number will appear in kilo

This SI Prefixes functions on the fact that the Standard International Prefixes are the same no matter what type of measurement is being done.

Answer 4

You don't need a graphing calculator - or any calculator, really.

All metric units are related by powers of 10. There are 1000 milligrams in a gram, for instance, and 1000 g in a kg.

Therefore, there are 1 000 000 mg in a kg.

Divide by 1 000 000 by moving the decimal six places to the left (right now it's invisible - just after the '8').

So, 478 mg = 0.000 478 kg
