Which of the following is the smallest unit of measurement?
Question: Which of the following is the smallest unit of measurement?
a) Millimeter b) Angstorm c) Fermi d) Meter
Millimeter, angstorm, Fermi and meter are different measuring units used to measure the length, height, distance, etc.
Answer: Option C - Fermi is the smallest unit of measurement.
Let's express each of these units in terms of meter to compare them.
We know that,
Meter is the SI unit of length
1 millimeter = 1/103 meter
1 angstorm = 1/1010 meter
1 fermi = 1/1015 meter
From the above relationships, it is clear that fermi will have the least value.
