Can I enter hours and minutes separately?

This calculator expects a single hour value. To convert hours and minutes, first turn the minutes into a decimal fraction of an hour (for example, 1 hr 30 min = 1 + 30/60 = 1.5 hours), then enter that number.

Does it support very small or very large values?

Yes. You can enter very small decimal hours (like 0.02 hours) or large values (like 100 hours); the tool simply multiplies by 60 to produce minutes.

How should I round for payroll or invoicing?

Rounding rules vary. Some organizations round to the nearest minute, others to 6‑minute or 15‑minute increments. Use this tool to get the raw minute value, then apply your specific rounding rules in a spreadsheet or billing system.

Hours to Minutes Converter

Turn fractional hours into total minutes for schedules, timesheets, or study plans.

Results

Minutes: 90.00

How to use this calculator

Enter the number of hours you want to convert. You can use whole hours (2, 3, 4) or include decimals (1.5, 2.75, 0.1).
Run the calculation to multiply your hours by 60 and produce total minutes.
Copy the minutes value into your timesheet, billing system, study plan, or scheduling tool.
If your system requires whole minutes, round the result to the nearest minute—or to the nearest 6 minutes, 15 minutes, etc.—based on your rules.

Inputs explained

Hours: Total hours to convert into minutes. You can enter decimals (for example, 1.25 hours for 1 hour 15 minutes, or 0.5 hours for 30 minutes) to represent partial hours.

How it works

We take the number of hours you enter (which can be an integer or decimal) and multiply it by 60 to convert to minutes.

Because hours × 60 is a linear conversion, partial hours (like 1.25 hr) become whole minutes (75 min) without any special cases.

The calculator keeps the minute value as a decimal number so you can decide how to round, if at all, for your particular use case.

Formula

Minutes = Hours × 60

When to use it

Turning decimal hours from time tracking software into minutes for billing, when an invoice or payroll system expects minutes instead of hour fractions.
Planning study, work, or workout blocks in minutes while still thinking in hour-based chunks.
Coordinating schedules when one party thinks in hours (like 1.25 hours) and the other uses minutes (like 75 minutes).
Converting course or meeting durations from hours to minutes for calendars, agendas, or reports.

Tips & cautions

If your starting data is in hh:mm format (for example, 1:30), first convert it to hours as a decimal (1 hour + 30/60 = 1.5 hours), then plug that into this converter.
Payroll and billing systems often round to specific increments (like 6 minutes or 15 minutes); apply that rounding after you see the raw minute result.
Keep a consistent unit within a spreadsheet or report—convert all durations to either hours or minutes so formulas are easier to reason about.
For very small time blocks, decimals can get messy; converting them to whole minutes often makes summaries more readable.
Does not split hours and minutes into a formatted hh:mm output—this tool focuses on total minutes. Use the minutes-to-hours converter for the reverse direction.
Assumes non‑negative time values; it is not designed for representing time zones, offsets, or negative durations.
Rounding behavior is up to you; the calculator does not enforce any particular rounding convention used by payroll or billing systems.

Worked examples

Example 1: 2.5 hours

You enter 2.5 hours.
Minutes = 2.5 × 60 = 150 minutes.
You can log 150 minutes in a system that doesn’t accept decimal hours.

Example 2: 0.75 hours

You enter 0.75 hours (45 minutes).
Minutes = 0.75 × 60 = 45 minutes.
This is useful when converting quarter‑hour billable increments into whole minutes.

Example 3: Small time blocks

You enter 0.1 hours.
Minutes = 0.1 × 60 = 6 minutes.
You can quickly see that a tenth of an hour corresponds to a 6‑minute time slice, common in legal and consulting billing.

Deep dive
