Data Storage Converter
Convert digital storage and data units
You're deciding how much cloud storage to buy for backing up your 4K videos. The backup software shows 250 GB per month, but your cloud plan options are listed in TB. Your internet speed is 50 Mbps, but download sizes are quoted in MB. You need conversions to understand how much you actually need and how long uploads will take.

Context
Data storage seems simple—bytes, kilobytes, megabytes—but confusion is rampant. Cloud providers advertise storage in TB; phones report available space in GB; download speeds are in Mbps while file sizes are in MB. High-resolution video (4K) generates enormous files: one hour of 4K video can be 100+ GB depending on codec and quality. When you're backing up a photo library (tens of GB), recording screen tutorials (GB per hour), or storing videos, understanding the relationships between storage units is essential.
Misunderstanding storage units leads to real mistakes: buying insufficient cloud storage, not realizing your internet speed is too slow for your workflow, or miscalculating how many SSDs you need. A 1 TB external drive might seem huge until you realize it holds about 10 hours of 4K video. Knowing the conversion between bits and bytes, understanding megabytes vs. megabits, and comparing storage tiers accurately means making informed decisions about backups, cloud plans, and hardware.

Why this matters
Choosing cloud storage for video backups
You record 4K videos (40 GB per hour). Your backup plan needs capacity for 10 hours per month. Cloud providers offer 100 GB, 1 TB, or 2 TB plans. You need to convert hours of video to GB to choose the right plan.
Estimating upload time based on internet speed
Your internet is 50 Mbps (megabits per second). You have a 250 GB backup to upload. You need to convert speed and file size to estimate upload time in hours.
Comparing SSD capacity when shopping for storage
SSDs are advertised as 256 GB, 512 GB, 1 TB, 2 TB. You have 600 GB of files to store. You need to understand how many GB each option holds and whether you have enough space.
Understanding available storage on your phone or computer
Your phone shows 64 GB storage, but the OS and apps take space. You're trying to understand how much space actual media (photos, videos) takes up in relation to the total.
Frequently asked
A cloud plan offers '1 TB of storage.' How many gigabytes is that? →
1 TB equals 1,024 GB. Use [Terabytes to Gigabytes](/data/terabytes-to-gigabytes/) for storage comparisons. Most cloud plans use 1 TB (1,000 GB for marketing) vs. 1 TiB (1,024 GiB technical). For practical purposes, 1 TB ≈ 1,000 GB and holds roughly 10 hours of 4K video.
My backup is 250 GB. How many TB is that? →
250 GB is 0.25 TB (or about 1/4 of a terabyte). Use [Gigabytes to Terabytes](/data/gigabytes-to-terabytes/) to determine which cloud plan you need. If you backup monthly, you need 3 TB per year (250 GB × 12 months), suggesting a 2 TB plan might be too small.
My internet speed is 100 Mbps. How long does it take to upload a 50 GB file? →
100 Mbps is 12.5 megabytes per second (MB/s). A 50 GB file takes about 67 minutes to upload. Use [Megabits to Megabytes](/data/megabits-to-megabytes/) for speed conversions, then divide file size by upload speed to estimate time. Real-world speeds vary, so add buffer.
One video file is 85 GB, another is 900 MB. How many times does the smaller fit into the larger? →
85 GB equals 87,040 MB, so the smaller file fits about 96.7 times. Use [Gigabytes to Megabytes](/data/gigabytes-to-megabytes/) to work with mixed units. This matters when organizing files or understanding storage capacity.
A 4K camera records at 50 Mbps bitrate. How much storage does 1 hour of video use? →
50 Mbps (megabits) is 6.25 MB/s (megabytes). One hour (3,600 seconds) × 6.25 MB/s = 22.5 GB. Use [Megabits to Megabytes](/data/megabits-to-megabytes/) for bitrate conversions. Different codecs and settings change this, but this gives you a realistic estimate for planning storage.
My phone shows 64 GB storage, but I can only store 40 GB of media. Why? →
The OS (iOS, Android), system apps, and cache take up roughly 20–25 GB of that 64 GB. Available storage = Total - OS - System Files. If you need more media space, choose a higher capacity model (128 GB, 256 GB, etc.). Each storage tier is roughly double the previous one.
