About Minutes to Decimal

What the site does

Most time is recorded as hours and minutes, but payroll and billing software multiply a rate by a decimal. This site does that one conversion in every form it comes in:

• Type a number of minutes into the homepage converter to get decimal hours.
• Turn a decimal back into minutes, or read it as hours and minutes on a clock face.
• Work from clock-in and clock-out times with a break, or from separate hours and minutes fields.
• See what time-clock rounding rules do to a shift, convert to tenths of an hour, or write a time the way Postal Service time records do.
• Print a 1 to 60 minute reference chart or look up every hundredth from 0.01 to 0.99.

Common minute and decimal values each have their own page as well, reachable from those two charts.

How the results are calculated

Every converter runs in your browser. Minutes become decimal hours by dividing by 60, and decimal hours become minutes by multiplying by 60. Results are rounded half up to the number of decimal places shown, and a four-decimal working value is printed beside each result so you can see what the rounding did.

Nothing you type into a converter is sent to this site's servers.

How every page is checked before it is published

Each time the site is rebuilt, an automated check reads every finished page and recomputes its numbers. It confirms that:

• each value page states the correct result, in the correct direction and unit;
• every number shown in a diagram or calculator matches the inputs it was drawn from;
• questions and answers on a page do not repeat each other or the page's own text;
• each page carries the structured data that matches its type;
• no internal link points to a page that does not exist.

If any of these checks fails, the build stops and nothing is published.

Where the real-world facts come from

Statements about payroll rules, postal timekeeping and spreadsheet software are checked against the original source before they are written. The sources behind the pages are:

• The federal time-clock rounding regulation, 29 CFR 785.48, as published by Cornell Law School's Legal Information Institute.
• ADP's Minutes to Hundredths Chart for hourly employees.
• USPS Notice 30, Time Conversion Table, as reproduced in the National Association of Letter Carriers' Postal Record, June 2025.
• Intuit's help article on time formats in QuickBooks Desktop Payroll.
• Microsoft Support on adding and subtracting time in Excel, and Google Docs Editors Help on the TIMEVALUE function.
• The French National Convention's decree of 4 Frimaire Year II (24 November 1793), in an English transcription.

A claim that could not be confirmed against a primary source was left off the site rather than softened.

What the site is not

The converters do arithmetic. They are not payroll, tax or legal advice. Whether and how your working time may be rounded depends on your employer's policy and the law that applies to you. Where a page describes a rule, it links to the source so you can read the rule itself.

Corrections and contact

If a figure looks wrong, email info@minutes-to-decimal.com with the page address, the value you entered and the result you expected. Reports are checked against the arithmetic and the sources above, and a confirmed error is corrected.

For anything else, use the contact page. How messages and site data are handled is set out in the privacy policy, and the conditions for using the site are in the terms of service.
