• What are the different units of length mentioned in the video?

  Nanometers, micrometers, millimeters, meters, and kilometers
• Why do we use different units of length?

  Each unit is 1,000 times bigger or smaller than the one next to it
• How do you convert 6 millimeters to meters?

  By dividing 6 by 1000 to get 0.006 meters
• What is the relationship between 6 millimeters and 0.006 meters?

  They represent the same value, just in different units
• How do you convert 0.006 meters to kilometers?

  By dividing 0.006 by 1000 to get 0.000006 kilometers
• How do you convert 6 millimeters to micrometers?

  By multiplying 6 by 1000 to get 6000 micrometers
• What is the conversion of 6 millimeters to nanometers?

  By multiplying 6 by 1,000,000 to get 6,000,000 nanometers
• How do you convert 340 nanometers to millimeters?

  By dividing it by 1,000,000 or by converting to micrometers first
• What is the conversion of 340 nanometers to micrometers?

  By dividing 340 by 1000 to get 0.34 micrometers
• What is the conversion of 0.34 micrometers to millimeters?

  By dividing 0.34 by 1000 to get 0.00034 millimeters
