I was helping a friend process weekly timesheets for her small business. She was manually converting hours and minutes to decimal format (like 7h 45m → 7.75 hours) to calculate payroll — dividing by 60 on a calculator, copying results to a spreadsheet, then double-checking her math. It was tedious and error-prone.
I searched for a time to decimal calculator and found dozens of tools, but most only showed the final result. If you needed to verify the calculation or share it with someone (like HR or a client), you had to redo the math yourself. That's when I decided to build something different.
The problem we're solving:
Most time converters treat you like a black box — input goes in, output comes out, but you can't see or export the calculation. For payroll, billing, or compliance, you need to prove how you got that number.
How our approach is different:
1. Transparent calculations — Every result shows the formula and step-by-step breakdown. Screenshot it, copy it, or export it.
2. Exportable records — Build timesheet, payroll, or billing tables with multiple entries, then export as CSV, Excel, or PDF. No more copying cell by cell.
3. Four tools in one — Time to Decimal, Decimal to Time, Timesheet/Payroll/Billing table, and Batch Converter. Most competitors only do the first one.
4. Payroll-ready features — Calculate regular hours, overtime (with adjustable limits and multipliers), and total pay. Billing mode for freelancers and consultants.
How it evolved:
I started with just the basic converter. Then I added the calculation breakdown because my friend needed to share results with her accountant. Then the table feature, because she was tracking multiple employees. Then export, because she needed to import the data into her payroll system. Each feature came from real use cases.
If you track billable hours, process payroll, or fill out timesheets — I'd love to hear how this fits into your workflow. What features would make it even more useful for you?
love that it shows the step-by-step breakdown, super useful when i need to explain things to clients or double check my billing numbers
The step-by-step breakdown is genuinely useful for double-checking payroll math before sending hours off to clients. Nice that the batch converter and CSV export are right there without needing an account.
Honestly really handy, I plugged in a payroll scenario and the step-by-step breakdown actually made me trust the numbers way more than just getting a final answer. Kinda weird how much I appreciate the no sign-up thing too.
the step by step breakdown is super useful for double checking timesheets before sending them out, honestly wish i had this months ago
Finally a simple tool that shows the math instead of just spitting out a number, the step-by-step view is genuinely useful for double checking. Payroll mode saved me a ton of time on a client invoice last week.
The step-by-step breakdown is a nice touch, makes it easy to verify payroll numbers before sending them off. Surprised the batch converter handled a whole timesheet without any fuss.
