Nanometers are used to measure extremely small lengths or distances. For example, 25,400,000 nanometers is only 1 inch.
Some of the standard instruments used to measure length are a ruler, meter scale, measuring tape, vernier caliper, and screw gauge. To measure very long lengths like the length of a road we use measuring tape
