A human hair is approximately 40 microns wide. If 1 micron is equal to 10−6 meters, and 1 nanometer is equal to 10−9 m, then how many nanometers wide is a human hair?
Q. A human hair is approximately 40 microns wide. If 1 micron is equal to 10−6 meters, and 1 nanometer is equal to 10−9 m, then how many nanometers wide is a human hair?
Convert to meters: Convert microns to meters. Since 1 micron equals 10−6 meters, multiply 40 microns by 10−6 to convert to meters.Calculation: 40 microns ×10−6 meters/micron = 0.00004 meters.
Convert to nanometers: Convert meters to nanometers. Since 1 meter equals 109 nanometers, multiply the result from the previous step by 109 to convert to nanometers.Calculation: 0.00004 meters ×109 nanometers/meter =40,000 nanometers.
