소개

Memory Card Capacity Calculator — Estimate photo count or video recording time for a memory card. Enter Card Capacity, Avg Photo File Size, Video Bitrate, Usable Capacity Factor to get an instant, accurate result.

공식

Photo count = (card capacity in GB × 1000 × usable-capacity factor) / average file size (MB). Video recording time (minutes) = (card capacity in GB × 8000 × usable-capacity factor) / video bitrate (Mbps), converting bytes of storage to bits of video data. A default usable factor of 0.93 accounts for formatting overhead and manufacturer GB-vs-GiB labeling.

단계별 안내

  1. Enter the Card Capacity.
  2. Enter the Avg Photo File Size.
  3. Enter the Video Bitrate.
  4. Enter the Usable Capacity Factor.
  5. Click Calculate to see your result instantly.

실제 예시

Example: With Card Capacity = 128 GB, Avg Photo File Size = 25 MB, Video Bitrate = 100 Mbps, Usable Capacity Factor = 0.93, the Memory Card Capacity Calculator gives Num Photos: 4761.6, Recording Time Minutes: 158.72.

자주 묻는 질문

Why isn't the usable capacity 100% of the rated card size?
Card manufacturers label capacity in decimal gigabytes (1 GB = 1,000,000,000 bytes), while formatting and file-system overhead reduce the space actually available — a 0.93 factor approximates this real-world usable capacity.
Can I estimate both photo and video capacity at once?
Yes, enter both an average photo file size and a video bitrate to see results for each side by side.
What inputs does the Memory Card Capacity Calculator need?
You'll need to provide: Card Capacity, Avg Photo File Size, Video Bitrate, Usable Capacity Factor. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Memory Card Capacity Calculator?
The Memory Card Capacity Calculator applies the formula exactly as calculated — Photo count = (card capacity in GB × 1000 × usable-capacity factor) / average file size (MB). Video recording time (minutes) = (card capacity in GB × 8000 × usable-capacity factor) / video bitrate (Mbps), converting bytes of storage to bits of video data. A default usable factor of 0.93 accounts for formatting overhead and manufacturer GB-vs-GiB labeling. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Memory Card Capacity Calculator free to use?
Yes, the Memory Card Capacity Calculator is completely free, requires no signup, and runs instantly in your browser.

The Memory Card Capacity Calculator uses a real, verifiable formula — Photo count = (card capacity in GB × 1000 × usable-capacity factor) / average file size (MB). Video recording time (minutes) = (card capacity in GB × 8000 × usable-capacity factor) / video bitrate (Mbps), converting bytes of storage to bits of video data. A default usable factor of 0.93 accounts for formatting overhead and manufacturer GB-vs-GiB labeling. — so results are accurate every time, not an approximation.
