Decimal Time Converter
Convert standard hours and minutes into decimal format and vice versa.
The Decimal Time Converter simplifies timesheet logging and payroll invoicing by converting between standard clock hours/minutes (HH:MM) and decimal hours. Since billing rates and payroll databases require decimal format (e.g. 7.5 hours instead of 7 hours and 30 minutes), this free converter helps you perform calculations instantly in both directions.

For Invoicing and Hourly Rates
Multiply hours directly by your billing rate. If you worked 4 hours and 15 minutes, entering 4:15 converts to 4.25 decimal hours, allowing you to multiply by your hourly rate (e.g., 4.25 × $50 = $212.50) without errors.
For Payroll Timesheet Logging
