IT電卓+ is a focused calculator for engineers, network administrators, and learners studying for IT certifications. Four common tasks are organized into simple, switchable tabs. [Unit Conversion] Convert between bit, B, KB, MB, GB, TB, and PB. Toggle between SI prefixes (base 1000) and IEC prefixes (base 1024 — KiB, MiB, etc.) so you can match the convention you need for storage, memory, or traffic. [Subnet Mask Calculator] Enter an IPv4 address and a CIDR value to get the network address, broadcast address, first and last usable host, subnet mask, wildcard mask, and host counts. /31 (RFC 3021) and /32 are handled correctly as special cases. [Base Conversion and Bit Operations] Convert between binary, octal, decimal, and hexadecimal. Binary output is grouped every four bits for readability. AND, OR, XOR, left shift, and right shift are available on the same screen. [Link Speed and Transfer Time] Convert across bps, Kbps, Mbps, Gbps, B/s, KB/s, MB/s, and GB/s. Combine a file size with a link rate to estimate how long a transfer will take. [16 languages] Available in 16 languages: Japanese, English, Simplified and Traditional Chinese, Spanish, Portuguese (Brazil), Korean, German, French, Hindi, Indonesian, Russian, Italian, Turkish, Thai, and Vietnamese. The app follows your device language. [Privacy] Calculations stay on your device. The app does not upload your inputs or results. [Price and ads] The app is free, with every feature available from the start. There are no in-app purchases or subscriptions. A banner ad is shown at the bottom of each screen. You choose whether ads may be personalized on first launch and can change it at any time under "Ad settings" in Settings.
