Days to Hours Converter

World's Simplest Time Tool

With this browser-based application, you can calculate how many hours there are in the given number of days. The application takes the input values (days), multiplies them by 24 and that converts them into hours. It supports both integer and decimal day values and it can convert multiple values at the same time. Created by computer nerds from team Browserling.

What Is a Days to Hours Converter?

This is a quick online utility for converting days to hours. One day is 24 hours and to convert days to hours, we simply do the multiplication operation: hours = days × 24. For example, 2 days is 2 × 24 = 48 hours and 5 days is 5 × 24 = 120 hours. You can convert not only full days to hours but also fractional day values. For example, 1.5 days is 1.5 × 24 = 36 hours and 4.6 days is 4.6 × 24 = 110.4 hours. You can enter multiple days in the input field (one value per line). In this case, they will all be computed in parallel and at once. The program also supports the postfix "days" or "d" for the input values and you can add the postfix "hours" to the output values. Timeabulous!

Full Days to Hours

This example calculates how many hours there are in 1 day, in one week (7 days), in one month (30 days), and in even longer time periods. To see all the results at once, we enter each individual day value on a new line. We also use the "days" suffix in the input and add the "hours" suffix to the output.

1 day 7 days 30 days 90 days 125 days 500 days
24 hours 168 hours 720 hours 2160 hours 3000 hours 12000 hours

Fractional Days to Hours

In this example, we convert five decimal fraction day values to hours. Conversion of partial days is similar to the conversion of full days – they are all multiplied by 24. We turn off the option that appends the "hours" string after the converted values and get only the numerical hour values in the output.

0.2 d 1.5 days 25.25 9.999 350.401
4.8 36 606 239.976 8409.624

Number of Hours in a Year

In the modern Gregorian calendar, a common year has 365 days and a leap year has 366 days. This makes the true average length of a year to be 365.242199 days. In this example, we load this number in the input field and convert it to the hours. It turns out that there 8765.812776 hours in an average year.
