Technology calculators
A decision map for data sizes, transfer time, passwords, number bases, and bandwidth cost. Start with three steps, then open a lane. The full index sits at the bottom.

High-intent tech utilities. Use these before the short index below.

Three IT jobs. One primary tool each.
01
Convert the data size
KB, MB, GB, and GiB are easy to mix. Convert the payload size before you estimate transfer time or storage cost.
Open data size converter →02
Estimate download time
Throughput and file size set how long a transfer takes. Use a realistic Mbps figure, not the marketing peak, for planning.
Open download time calculator →03
Generate a stronger password
Short reused passwords fail first. Generate a long random secret and store it in a password manager instead of a spreadsheet.

Decision lanes
Pick the job you have. Each lane points to the matching tool.
Tools by lane
Data size and bases
- Data size converter
KB, MB, GB, and binary prefixes.
- Binary / hex converter
Base conversions for debugging.
Transfer time and cost
- Download time
File size and speed to duration.
- Bandwidth to cost
Usage sketch vs billed bandwidth.
Passwords
- Password generator
Random passwords with length controls.
Gotchas before you ship
Short warnings with a tool handoff.
Decimal and binary prefixes differ
1 GB (10^9) is not 1 GiB (2^30). Storage vendors and OS dialogs often disagree. Convert with the prefix the tool or vendor uses.
Data size →Peak Mbps is not sustained Mbps
Download time estimates fail when you use the ISP's peak number. Use a measured average for planning.
Download time →Generated passwords still need storage
A strong password you cannot retrieve is locked out forever. Save it in a manager; do not email it to yourself in plaintext.
Password →Bandwidth bills have floors and overages
A simple GB × rate model can miss minimums and tiers. Treat the cost sketch as a planning bound, then check the invoice rules.
Bandwidth cost →Related hubs
