Conversion of SI units by using dimensional analysis

Question

1.) 525,000 mcg to dag

2.) 0.000215 daL to ul

3.) 0.0001 dm to nm

4.) 254,325 cm to um

Answer 1

Please be sure to check the math for all the following:

525,000 ug x 1 g / 10⁶ ug x 1 dag / 10 g = 0.0525 dag (decagrams) = 5.25x10^-2 dag

0.000215 daL x 10 L /1 daL x 10⁶ uL / L = 2.15x10⁴ uL

0.0001 dm x 1 m / 10 dm x 10⁹ nm / m = 1x10⁴ nm

254,325 cm x 1 m / 100 cm x 10⁶ um / m = 2.53225x10⁹ um
