The System Usability Scale (SUS) is a commonly used 10-item measure (with a 5-point scale) of subjective perceptions of technology usability. To calculate the total SUS score, the responses to all 10 SUS questions are re-scaled and/or re-scored in a way that all items had values from zero to 4 with 4 being the most positive. These converted scores are added and then multiplied by 2.5 to convert the range of possible values 0-100 (instead of from 0 to 40). Higher scores are better.
