> Convert hours (h) to minutes (min): 1 hour = 60 min, so multiply by 60 or divide by 0.016666667. Both fields are editable, so you can also type in minutes and get hours back.

## Inputs

- Hours (h)

## Results

- Minutes

## Formula

```
1 h = 60 min
1 min = 0.016666667 h
min = h × 60
```

## Explanation

Multiply hours by 60 to get minutes. Decimal hours from timesheets (1.75 h) are easier to read as minutes (105 min).

### How to use the Hours to Minutes Converter

- Type the number of hours into the **Hours** field. Decimals such as 0.75 are fine.
- Read the answer in **Minutes** – it updates as you type, with no button to press.
- To convert the other way, type into **Minutes** and the hours are recalculated.
- Press **Copy results** to copy both values with the page title, or **Copy link** to share this exact conversion.

This page converts only h ⇄ min. Need a different unit? Use the general time converter, where you can choose any “from” and “to” unit.

### How it works

Both units measure time, so they are always in the same ratio: one hour equals 60 minutes. The calculator multiplies the number of hours you type by 60 to give minutes, and when you type into the minutes field it divides by the same factor to give hours. Because the ratio never changes, doubling the hours always doubles the minutes. Results are calculated at full precision and rounded only for display (up to eight decimal places, with very large or small values shown in scientific notation).

### How to convert hours to minutes

- Write down the value in hours, for example **1.5 h**.
- Multiply by the conversion factor 60 (because 1 hour = 60 min).
- 1.5 × 60 = **90 min**.
- To go back from minutes to hours, divide by 60 – or multiply by 0.016666667.

### What is an hour?

An hour is 60 minutes or 3,600 seconds. Wages, shifts and travel times are counted in hours.

### What is a minute?

A minute is 60 seconds. The base-60 split of hours and minutes comes from ancient Babylonian astronomy.

### Common mistakes to avoid

Treating every month as 30 days or every year as 365 days in long calculations, and writing decimal hours such as 1.5 h as 1 h 50 min (it is 1 h 30 min).

## Worked example

Inputs — Hours: 1.5 h.

Results — **Minutes = 90 min**.
