What does SPM stand for?

• A. Strokes per minute
• B. Seconds per minute
• C. Strokes per second
• D. Steps per minute

Answer: (A)

Strokes per minute describes how many times you perform a brushing or stroking action in one minute. It uses the action (strokes) and a time unit (minute) to express a rate, which is exactly what SPM stands for. The other options don’t fit for this measure: seconds per minute would be redundant and not describe a rate of an action; strokes per second uses a different time unit (per second) and would change the rate; steps per minute refers to steps rather than strokes.
