Unit Conversion Techniques

Melissa Maribel guides students through converting 55 miles per hour to nanometers per second. The process is broken into two steps: converting miles to nanometers and hours to seconds, using appropriate conversion factors. The tutorial emphasizes the importance of aligning units for cancellation and rounding the final result to two significant figures. Melissa encourages practice and determination for exam success.
