Logging 5 Minute Time Increments
Overview:
5-minute increments are easier to communicate, but they don't convert cleanly into decimals.When converting 5 minutes to hours:- 5 ÷ 60 = 0.0833... (a repeating decimal)
- Rounded to two decimal places, this becomes 0.08, which equals 4.8 minutes (0.08 × 60), not a full 5 minutes.
This small difference can impact billing accuracy, especially when multiplied by an hourly rate.To ensure accurate and consistent billing, time must be converted into rational decimals.6 minutes = 0.1 hours, a clean decimal that avoids rounding issues.
