## anonymous one year ago how do you convert 7.02mg to dg

So mg means milligrams and dg means decigrams. How much smaller is a milligram than a gram? Do you know? (I want to make sure I'm not just giving you the answer) :)

2. anonymous

no that why I need help

3. anonymous

4. anonymous

I'm here! :)

5. anonymous

so I have a quiz on Tuesday which is on converting factor and density which I am bad at

6. anonymous

Okay, so here's what you need to know. There are 1,000 milligrams in a gram.

7. anonymous

And there are 10 grams in a decigram, so there are 10000 milligrams in a decigram.

8. anonymous

okay

9. anonymous

$7.02mg*1dg/1000$

10. anonymous

so the answer will be 0.00702dg

11. anonymous

yes or no

12. anonymous

It should be! :)

13. anonymous

cool okay next one is 0.600m to Ft

14. anonymous

1.9685 feet

15. anonymous

okay but how do I solve it

16. anonymous

Honestly... I have NO idea... I just used an online converter for that one. Let me find you a formula. :)

17. anonymous

So 1 meter = 3.28 feet.

18. anonymous

okay

@misaki12 you mean decigrams right?

20. Photon336

Well if so always start from the conversion factor ask yourself mg = miligrams dg = decigrams We are asked to convert 7.02 mg to decigrams right?

21. Photon336

$\frac{ 1 decigram }{ 100 miligrams }$

22. Photon336

always ensure that the factor you want to cancel out is in the denominator and that's milligrams. we have 7.02 milligrams so that's why we set up the conversion factor with milligrams in the denominator

23. Photon336

$7.02 miligrams *\frac{ 1 decigram }{ 100 miligrams }$

24. anonymous

that what i did

25. Photon336

|dw:1442548698684:dw|

26. Photon336

@Misaki12 see how I did this?

27. anonymous

okay so instead of the 1000 milligram I should use 100mg

28. anonymous

okay

29. Photon336

@Misaki12, you see why I set it up that way right? how the milligrams cancel out and I'm left with decigrams in the end, that's the point of dimensional analysis, always look for the conversion factor first and ensure that the unit you want to get rid of is in the denominator while the unit you want in this case decigrams is in the numerator.

okay

31. anonymous

thank you

32. Photon336

No problem, welcome to open study

33. anonymous

thank you
