Labor guides, such as Mitchell , All Data and Chilton use a decimal system based on hours and tenths of an hour (6-minute increments) to standardize repair times. Each 0.1 equals 6 minutes, allowing for precise, consistent billing and technician payment.

So, as an example, 1.5 hours = 1 hour and 30 minutes (90 minutes).

The system ensures the job is billed at the actual time, not arbitrarily rounded up to a full hour, providing fair, consistent pricing.

We use All Data Pricing at our school shop.
