This article explains how the calculator functions, enabling you to perform calculations independently. It covers essential definitions, provides examples, shares relevant formulas, and includes tables and answers to frequently asked questions.

Definitions

Let’s get started by understanding the key definitions. Understanding these terms will allow you to perform conversions confidently.

What is storage capacity?

The capacity of a storage device refers to the maximum amount of data it can store. It is sometimes called storage space. The higher capacity means you can store more documents, pictures, videos, software, or games on the drive.

SSD and hard disk drives often don't meet their manufacturers' storage capacity claims. You can use our actual disk drive capacity to determine the real capacity of your storage.

What is storage capacity or file size unit?

Storage capacity and file size units are measurements used to measure how much data storage devices can hold and how big the files on these devices are.

Byte is a basic unit used to measure the drive capacity. There are also larger units to measure larger file size or drive capacity, including Kilobytes (KB), Megabytes (MB), Gigabytes (GB), and Terabytes (TB).

On top of that, there are also two different sets of units for data storage, including decimal and binary units.

Decimal (SI) units

The decimal units defined by the International System of Units (SI), based on powers of 10, have the following prefixes:

  • 1 Kilobyte (KB) = 1,000 bytes
  • 1 Megabyte (MB) = 1,000 KB
  • 1 Gigabyte (GB) = 1,000 MB

For the rest of the decimal units and its multiplier, please check the SI prefixes table below:

Binary (IEC) units

On the other hand, the binary units defined by the International Electrotechnical Commission (IEC), based on powers of 2, have the following prefixes:

  • 1 Kibibyte (KiB) = 1,024 bytes
  • 1 Mebibyte (MiB) = 1,024 KiB
  • 1 Gibibyte (GiB) = 1,024 MiB

For the rest of the binary units and its multiplier, please check the binary (IEC) prefixes table below:

Formulas

To find out how many documents of a specific type can fit in your device's storage, start by converting the storage and the document file size into bytes. Since the byte is the base unit, this measurement remains consistent whether you are using decimal or binary calculations.

Convert to bytes

So, to convert storage and file sizes to bytes, multiply the size by its corresponding multiplier based on the unit of measurement.

$$\text{N}_{\text{B}} = \text{Storage or File Size} \times \text{Multiplier}$$

Determine the number of documents

Now that we have determined the storage capacity and the file sizes in bytes, we can calculate how many documents can fit into the device's storage. To do this, divide the total storage capacity by the size of a single document file.

$$\text{Number of Documents} = \frac{\text{Storage Capacity}_{\text{(B)}}}{\text{Document Size}_{\text{(B)}}}$$

Examples

Let's examine examples illustrating the calculations needed to determine how much content you can fit in a device's storage.

Example: Determine how many photos can fit in a 512GB iPhone.

Sarah is an enthusiastic photographer who loves capturing life's moments with her iPhone. She often shoots high-resolution photos. She upgraded her iPhone to the latest model with 512GB of storage.

She wants to know how many photos her new iPhone can store before she needs to delete old photos to free up space. She also needs space for the iOS operating system, apps, and games, a total about 50GB.

Calculations:

  • Available storage space for photos: 512GB - 50GB = 462GB

To calculate the total amount of photos that can fit on a 462GB storage:

$$\text{Number of Photos} = \frac{\text{Storage Capacity}_{\text{(B)}}}{\text{Document Size}_{\text{(B)}}}$$

Where:

So,

$$\text{Number of Photos} = \frac{462{,}000{,}000{,}000}{2{,}000{,}000} = \boxed{231{,}000}$$

Therefore, her new 512GB iPhone can store up to 231,000 high-quality photos while having 50GB spare for operating systems, apps, and games.
