Answer: The conversions are given below.
Step-by-step 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
- For Option 3:

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

So,

Hence, the correct value is

- For Option 4: 12.53456 kg
The given value is already in its S.I unit.
Hence, the correct value is 12.53456 kg
