This tool calculates the viewing time of videos and other media by playback speed.

• Enter the length of the original video and it will automatically calculate the viewing time for each playback speed.
• Calculation results are rounded to the nearest millisecond.

## How to calculate viewing time

Viewing time = Play time / Playback speed

e.g. Play time = 2 h (7200 s)

### 1.25x

7200 / 1.25 = 5760 s
5760 / 60 / 60 = 1 mod 2160 = 1 h
2160 / 60 = 36 mod 0 = 36 m 0 s
= 01:36:00

### 1.5x

7200 / 1.5 = 4800 s
4800 / 60 / 60 = 1 mod 1200 = 1 h
1200 / 60 = 20 mod 0 = 20 m 00 s
= 01:20:00

### 1.75x

7200 / 1.75 = about 4114 s
4114 / 60 / 60 = 1 mod 514 = 1 h
514 / 60 = 8 mod 34 = 8 m 34 s
= 01:08:34
