Whether you have a monthly contract or are on a “Pay As You Go” data plan, usage is most likely measured and charged by the megabyte or MB
So…
What is a megabyte (MB)? or kilobyte (kB)? or gigabyte (GB)?
So…
What is a megabyte (MB)? or kilobyte (kB)? or gigabyte (GB)?
This still isn't much help unless you know what this means in terms of an amount of text, a number of images or minutes of video. So let’s try and put it in a way that relates to how we typically consume data.
How much data do I need?
It depends! There are many factors at play here, the most significant of which is your own data usage habits.
This is why you need to a tool like datasquasher to track and control your data consumption.
Once you start streaming audio and videos the figures will soon add up.
Many people will be reluctant to stream videos using their 3G/4G connections, mainly due to poor reception or coverage in their area, or simply because they are unsure of how much data they will use (a symptom known as Bill Shock Avoidance).
Below are some guidelines and examples to help you measure your data usage:
Please note: these are just guidelines and your data usage will vary depending on the type of device you use. Connection speed will also play a factor in affecting the above figures.

Below are some guidelines and examples to help you measure your data usage:
- One Text email (about 2000 English characters): 22kB
- One email with one photo attachment: 1.5MB
- One web page (mobile version): 180KB
- Music streaming (average quality, 160Kbps): 1.2MB per minute, 72MB per hour
- Music streaming/downloading (320Kbps): 2.4MB per minute, 144MB per hour
- BBC iPlayer video: 50MB to 350MB per hour
- BBC iPlayer radio: up to 60MB per hour
- YouTube video, HD: 300MB per hour
- Netflix video, SD: up to 1GB per hour (1024MB)
- Netflix video, HD: up to 2.3GB per hour (2,400MB)

Websites
The data consumed when looking at a website on your mobile varies hugely depending on the mix of text, images and video and whether the site has been optimized for use on a mobile device. Here are some examples:

Images
Image quality and size have a significant impact on data usage. Nearly every website, whether it's a desktop or mobile-optimised site, will have numerous images that can consume a sizeable amount of your data allowance.

Sending images via email and instant messaging apps also use up your mobile data. The image quality you choose when sending an image (Original, Large, Medium or Small) makes a big difference to the data you use.
Added to this, sending images (or video) uses more data than the photo file size as the photo needs to be converted to travel by email ( + see below for a bit of “tech speak” that explains this).
+ Why more data is used to send an image or video
Sending email is text based, using SMTP (Simple Mail Transfer Protocol). This was around before the Internet as we know it today, so a way of being able to send binary data (for images, videos & other attachments) also had to be found.
To do this, binary files are encoded into a text-based format. Because each text character can only hold a small amount of data, more is needed to represent the same file. Most files are encoded using MIME:
