Good to know: Mbps = megabits per second (speed). GB = gigabytes (amount). 8 bits = 1 byte, so 8 Mbps moves about 1 MB each second.

How to use it (step by step)

  1. 1Fill in the boxes: “Calculate for”, “Viewers (stream) or monthly visitors (site)”, “Bitrate in Mbps (stream) or pages per visit (site)”, “Hours (stream) or MB per page (site)”. Example numbers are already there so you can see how it works; replace them with yours.
  2. 2The result updates instantly as you type (on a phone it is below the boxes).
  3. 3The bold line is the main answer. Tap Copy next to any value to copy it.

Words to know

Pace / speed
Speed = distance per hour (km/h). Pace = time per distance (minutes per km), common in running.
Mbps
Megabits per second: how fast data flows. 25 Mbps is enough for HD streaming. Divide by 8 to get megabytes per second.
Bitrate
How much data a video uses per second. Higher = sharper but bigger file.
Data storage units
Sizes of digital files: 1 KB ≈ a short text, 1 MB ≈ a photo, 1 GB ≈ a movie. 1 GB = 1,000 MB (or 1,024 in computer counting).
Time card / hours
Adding up hours worked (minus breaks) to calculate pay. Overtime is time beyond normal hours, often paid at a higher rate.
Byte
The basic unit of computer storage. One basic letter = 1 byte in UTF-8; ñ = 2 bytes; most emoji = 4 bytes.
