1. convert each of the following measurements to the si base the equal sign after the problems illustrates my answer that i got from doing the problems myself. can someone very if i got the answer right, and if not explain why and the process of getting the right answer 45mg=.045
125ns=.125
10.7ul=.107
12.53456kg=12,534.6

The conversions are given below.

Explanation:

Unit is defined as the quantity that is used as a standard for measurement.

S.I unit of mass if kilograms.

S.I unit of time is seconds.

S.I unit of volume is cubic meters.

The given conversions are not correct.

Converting this into kilograms, we use the conversion factor:

So,

Hence, the correct value is 0.000045 kg

Converting this into seconds, we use the conversion factor:

So,

Hence, the correct value is 0.000000125 ns

Converting this into cubic meters, we use the conversion factor:

So,

Hence, the correct value is

The given value is already in its S.I unit.

Hence, the correct value is 12.53456 kg
