About Data & Digital Converters
The Data & Digital category contains two converters that address the most frequent data-related measurement questions: file and storage sizes, and network transfer speeds.
Storage sizes: the decimal vs binary divide
The most persistent source of confusion in data storage is the gap between how manufacturers measure capacity (using decimal SI prefixes: 1 KB = 1,000 bytes) and how operating systems historically reported it (using binary IEC prefixes: 1 KiB = 1,024 bytes). The discrepancy grows with scale: a 1 TB hard drive contains 1,000,000,000,000 bytes, which is only 909 GiB — so Windows historically showed it as "909 GB" while the box said "1 TB."
The Data Storage Converter includes both unit systems clearly labelled, so you can switch between SI units (KB, MB, GB, TB) and IEC binary units (KiB, MiB, GiB, TiB) to reconcile manufacturer specifications with what your operating system reports.
Transfer rates: bits vs bytes
Internet service providers measure bandwidth in megabits per second (Mbps) while download managers and file browsers show progress in megabytes per second (MB/s). Since 1 byte = 8 bits, a 100 Mbps connection delivers at most 12.5 MB/s — a factor-of-8 difference that regularly confuses users who expect their "100 Mbps" plan to download 100 MB per second.
The Data Transfer Converter converts between bit-per-second units (Kbps, Mbps, Gbps) and byte-per-second units (KB/s, MB/s, GB/s), along with common ISP plan speeds for quick reference.

Frequently Asked Questions
What data converters are available in this category?
The Data & Digital category includes two converters: the [Data Storage Converter](/data-storage-converter/) for file sizes and drive capacities (bits, bytes, KB, MB, GB, TB, PB), and the [Data Transfer Converter](/data-transfer-converter/) for network and internet speeds (Kbps, Mbps, Gbps, MB/s, GB/s). Together they cover the two most common data measurement questions: 'how large is this file?' and 'how fast is this connection?'
What is the difference between MB and MiB?
MB (megabyte) in the SI definition equals 1,000,000 bytes (10⁶). MiB (mebibyte) equals 1,048,576 bytes (2²⁰). Storage manufacturers use the SI definition (so a '1 TB' hard drive holds 1,000,000,000,000 bytes), while operating systems historically used binary definitions (showing the same drive as ~931 GiB). The [Data Storage Converter](/data-storage-converter/) includes both SI and binary (IEC) units so you can check both.
How do I convert Mbps to MB/s for download speed?
Divide Mbps by 8 to get MB/s. A 100 Mbps internet connection downloads at 100 ÷ 8 = 12.5 MB/s. This is because 1 byte = 8 bits. Internet speeds are measured in megabits per second (Mbps) by ISPs, while file sizes and download progress bars show megabytes (MB). The [Data Transfer Converter](/data-transfer-converter/) handles this conversion along with Kbps, Gbps, and byte-per-second variants.
How long will it take to download a file given my internet speed?
Divide file size in MB by download speed in MB/s. For a 4 GB (4,000 MB) file on a 100 Mbps (12.5 MB/s) connection: 4,000 ÷ 12.5 = 320 seconds, approximately 5 minutes 20 seconds. Use the [Data Transfer Converter](/data-transfer-converter/) to convert your ISP speed from Mbps to MB/s first, then divide your file size accordingly. Actual download time may be longer due to network congestion, server limitations, and protocol overhead.
What is the storage capacity of a typical smartphone in India?
Smartphones sold in India in 2024–25 range from 64 GB (budget segment) to 512 GB or 1 TB (premium flagships). In practice, 64 GB is approximately 59.6 GiB as shown by the operating system after accounting for the binary vs decimal discrepancy. Out of the box, the operating system and pre-installed apps consume 10–20 GB, leaving 40–50 GB usable on a 64 GB phone. The [Data Storage Converter](/data-storage-converter/) can help you compare capacities across different unit representations.
What internet speeds are common in India and what do they mean in practice?
Typical home broadband plans in India offer 50 Mbps, 100 Mbps, 200 Mbps, and 1 Gbps. In practical terms: 50 Mbps = 6.25 MB/s (downloads a 1 GB file in ~2.7 minutes), 100 Mbps = 12.5 MB/s (1 GB in ~1.3 minutes), 1 Gbps = 125 MB/s (1 GB in ~8 seconds). Mobile 5G connections in India can reach 300–500 Mbps peak, though average real-world speeds are lower. Use the [Data Transfer Converter](/data-transfer-converter/) to benchmark your plan.
What does 1 petabyte mean in practical terms?
1 petabyte (PB) = 1,000 terabytes = 1,000,000 gigabytes = 1 trillion kilobytes. In practical terms, 1 PB can hold approximately 200,000 hours of HD video, 20 billion MP3 songs, or 500 billion pages of standard printed text. Data centres and enterprise storage systems deal in petabytes; consumer storage currently peaks at 20–22 TB per drive. The [Data Storage Converter](/data-storage-converter/) covers units from bits through exabytes.
Why do file sizes shown by Windows and macOS differ from the advertised drive capacity?
Drive manufacturers label capacity using SI (decimal) units: 1 TB = 1,000,000,000,000 bytes. Windows historically displays capacity using binary units but labels them incorrectly as GB (it actually shows GiB): 1 TiB = 1,099,511,627,776 bytes. So a '1 TB' drive appears as ~931 GB in Windows. macOS has used SI units since macOS 10.6 (Snow Leopard, 2009), matching manufacturer labelling. This is why the same drive shows different sizes in different operating systems.
What is the difference between data transfer rate and bandwidth?
Bandwidth is the theoretical maximum data rate a connection can carry (e.g. 100 Mbps for your ISP plan). Throughput is the actual data rate achieved in practice, which is always lower due to protocol overhead, network congestion, server bottlenecks, and Wi-Fi signal limitations. The [Data Transfer Converter](/data-transfer-converter/) works with bandwidth figures as advertised — multiply by 0.7–0.9 for a realistic estimate of actual download speeds.
How much data does streaming HD video consume?
Standard HD (1080p) streaming on platforms like Netflix typically uses 3–5 GB per hour; 4K HDR streams consume 7–15 GB per hour. On a 50 Mbps connection (6.25 MB/s), a 5 GB/hour stream requires only about 11.1 Mbps on average — well within the connection's capacity. Mobile streaming on lower quality (480p) uses approximately 0.5–1 GB per hour. The [Data Storage Converter](/data-storage-converter/) can help you calculate how many hours of video will fit on a given storage device.
What is the largest standard unit of digital storage?
The largest named unit in standard use is the yottabyte (YB) = 10²⁴ bytes = 1 trillion terabytes. Practically, storage discussions rarely go above petabytes for enterprise use or exabytes for global data estimates. The [Data Storage Converter](/data-storage-converter/) covers units from bits through petabytes, which encompasses all practical consumer and enterprise scenarios.
