What unit would be the most appropriate to use when measuring(in S1 units)the length of a pencil
meters (not kilograms or seconds)
I'd use centimeters or millimeters.
To measure the length of a pencil in S1 units, the most appropriate unit to use would be meters (m).
To find the length of the pencil, you can follow these steps:
1. Place the pencil on a flat surface.
2. Take a ruler or a measuring tape and align it along the length of the pencil.
3. Starting from one end of the pencil, read the measurement where the other end of the pencil aligns with the ruler or measuring tape.
4. Note down the measurement in meters.
If the measurement is less than a meter, you can use smaller units like centimeters (cm) or millimeters (mm) to express the length more precisely.
Remember, S1 units refer to the International System of Units (SI units), which is the most widely used system of measurement worldwide.
