Live result1.5 h1 h 30 min · rounded to nearest 15 min: 90 min

Formula used

Decimal hours = total minutes ÷ 60. Whole hours = floor(total minutes ÷ 60). Remaining minutes = total minutes − whole hours × 60.

This is the method behind the answer, so the result can be checked rather than simply trusted.

Assumptions used

What this answer assumes

Best for turning a total minute count into decimal hours without hiding the original duration.

One hour is treated as exactly 60 minutes.
The main result is the unrounded duration; any timesheet or billing rounding should be applied separately.
The calculator converts a duration, not a clock time, timezone-aware timestamp or calendar interval.
This page uses transparent general arithmetic and does not claim a payroll, legal or billing standard.

Master’s Tip

How to use the result well

Master’s Tip: if the result is going into payroll, invoicing or a job sheet, keep the original minute total beside the decimal hours. Rounding to 6, 10 or 15-minute blocks is a policy choice, not part of the raw conversion.

Rounding after conversion

The exact result stays 1.5000 hours. These rows show what happens if a timesheet, invoice or app later rounds to 15-minute blocks.

Hour segment view

The blue segment shows the minutes remaining inside the current hour after whole hours are separated. Decimal hours are still calculated from the full minute total divided by 60.

Visual grid

This result is a slice of the working week

Hours and minutes are micro-time. Mapping them onto a week shows how a simple total becomes part of payroll, breaks, overtime thresholds and workday rules.

Inputs

Minutes: 90 min
Optional rounding increment: 15 minutes

Method

Decimal hours = total minutes ÷ 60. Whole hours = floor(total minutes ÷ 60). Remaining minutes = total minutes − whole hours × 60.

90 minutes ÷ 60 = 1.5 decimal hours. The whole-hour part is floor(90 ÷ 60) = 1 hour, with 90 − 60 = 30 minutes remaining, so the same duration is 1 h 30 min.

Assumptions

One hour is treated as exactly 60 minutes.
The main result is the unrounded duration; any timesheet or billing rounding should be applied separately.
The calculator converts a duration, not a clock time, timezone-aware timestamp or calendar interval.
