Illustrative example
Representation before price
- Source A
- 01:30 HH:MM = 90 min = 1.50 h
- Source B
- 1.30 decimal h = 78 min = 01:18
- One minute display
- 0.0167 h / 0.02 h
- Evidence retained
- Original minute count and format specification
Fictional quantities; display precision is not approval to bill a different duration.
See the recorded product workflowDecisions to make before billing
Time conversion is a representation check before pricing. Confirm whether an export contains decimal hours, hours:minutes, whole minutes or another unit. Do not infer a format from a familiar-looking number, especially when 1.30 could be misread as one hour thirty minutes.
Keep the source export intact and write the transformation beside each reviewed quantity. Converting 90 minutes to 1.50 decimal hours preserves the quantity; displaying one minute as 0.02 hours introduces a precision limit. That display decision is separate from an approved billable rounding increment.
The fictional review compares HH:MM 01:30 with decimal 1.30. They represent 90 and 78 minutes respectively. The converter keeps forward and reverse entries independent, so the reviewer must not assume a two-decimal display will reconstruct the original exact minute count.

Outcome
Use this page to move from general research into a calmer, more repeatable invoicing process.
Work through the billing decision
Verify source and destination units
Use the export's format evidence and the invoice quantity specification. Retain the raw file, work references and period before any conversion.
Calculate and record precision
Convert whole hours and minutes to decimal hours or independently check decimal hours as a duration. Preserve exact source values and record display precision and any discrepancy.
Apply only approved billing decisions
Check work eligibility, rates and any separately agreed rounding transformation. Compare final invoice quantities with the reconciliation, assigning unexplained differences before release.

Treating 1.30 as thirty minutes after the hour
In decimal format it is eighteen minutes after the hour. The unit must come from evidence.
Avoid this
Rounding before summing without a policy
Display conversion can alter totals when repeated across rows. Preserve original values and follow the approved billing method rather than choosing a larger result.

Questions people usually have before changing the workflow.
Is this a payroll conversion guide?
No. It addresses service-invoice representation; employment and payroll rules require their own process.
Does reverse conversion accept more than two decimals?
The companion tool accepts two-decimal input and rounds to a whole minute. Preserve higher-precision source evidence separately.
Are rates needed for conversion?
No. Establish the correct quantity first, then apply the approved pricing basis in the invoice workflow.
