FAQ
About Digital Utilities.
SI (kB) or binary (KiB) — which do you use?
Both. Every converter accepts SI (kB, MB, GB) and IEC binary (KiB, MiB, GiB). You pick the units and we handle the base-1000 vs base-1024 math correctly.
How do you estimate download & upload time?
t = (bytes × 8) / (bandwidth × (1 − overhead)). You control the overhead % to account for TCP framing, retransmits, and real-world losses. Default overhead is 10%.
What bitrate defaults do you use for streaming?
Industry-typical values (Mbps): audio 0.128 / 0.32; SD video 3; HD 720p 5; FHD 1080p 8; 4K 25; 8K 80. Multiply by concurrent viewers for total egress bandwidth.
How is PPI/DPI calculated for a screen?
PPI = √(width² + height²) / diagonal inches — the standard ISO definition. This works for any monitor, phone, or tablet.
