IT電卓+
Specialized calculator for IT
Free · Designed for iPad. Not verified for macOS.
A single tool for the calculations IT pros run every day: data unit conversion, subnet masks, base conversion, and link speed and transfer time. SI and IEC supported.
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.
[Languages]
Japanese and English.
