Which is the smaller unit

Millimeter or nanometer

The nanometer is the smaller unit.

The smaller unit between millimeter (mm) and nanometer (nm) is the nanometer.

1 millimeter is equal to 1,000,000 nanometers.

To determine which unit is smaller, millimeter (mm) or nanometer (nm), we need to compare their values.

The metric system is based on powers of 10, where each successive unit is 10 times smaller or larger than the previous one.

A millimeter (mm) is equal to 1/1000th of a meter. Since "milli" means one thousandth, there are 1,000 millimeters in one meter.

On the other hand, a nanometer (nm) is equal to 1/1,000,000,000th of a meter. Since "nano" means one billionth, there are 1,000,000,000 nanometers in one meter.

Comparing these values, we see that a nanometer is smaller than a millimeter. In fact, there are one million nanometers in a millimeter.

So, in terms of size, the nanometer (nm) is the smaller unit compared to the millimeter (mm).
