The video tutorial explains how to calculate angular and linear speed through unit conversion. It starts with a wheel rotating at 4 revolutions per minute, converting this to angular speed in radians per minute. Then, it calculates linear speed using the wheel's diameter. The tutorial progresses to a more complex problem, converting a vehicle's speed from miles per hour to revolutions per minute, using the tire's diameter. The video emphasizes understanding unit conversion to solve these problems effectively.
