Advanced programmer calculator with binary, hex & octal modes, partition size calculator, bitwise operations, and memory allocation tool — built with bit-level accuracy for device engineers and Android developers.
Purpose-built for low-level programming, device engineering, and Android ROM development.
Full binary, hexadecimal, octal, and decimal calculator with live base conversion across all four number systems simultaneously.
Calculate Android partition sizes — boot, system, userdata, cache, recovery — with a visual partition layout builder and preset device profiles.
AND, OR, XOR, NAND, NOR, XNOR, NOT operations with live results in all number bases. Essential for register manipulation and flag masking.
Left/right logical shifts and circular rotate operations with instant results — critical for embedded programming and hardware register access.
Convert between bits, bytes, KB, KiB, MB, MiB, GB, GiB, TB, and TiB — covering both SI (decimal) and IEC (binary) standards.
Calculate 2's complement for signed integers in 8, 16, 32, and 64-bit word sizes. Displays binary, hex, and unsigned equivalents.
Interactive 32-bit visual display showing each bit individually. Click any bit to toggle it and see the result update in real time.
Full keyboard input support for fast calculation workflow — no need to use the mouse. Type numbers and operators directly.
When working with Android firmware, embedded systems, or low-level device engineering, standard calculators fall short. Partition sizing requires converting between megabytes, sectors, and blocks. Memory allocation demands binary precision. Bootloader configuration relies on hexadecimal addresses. This developer calculator addresses all of these needs in one place — free, no login required, and built specifically for engineers and ROM developers.
The programmer mode provides a full binary calculator supporting 8-bit, 16-bit, 32-bit (DWORD), and 64-bit (QWORD) integers. Enter any value in decimal, hexadecimal (0x), binary (0b), or octal prefix and all four number bases update simultaneously. This is invaluable when reading CPU registers, IMEI blocks, NVRAM addresses, or partition table offsets in scatter files.
The Storage/Partition tab provides a full storage unit converter (bits through TiB) and an interactive partition layout builder. Load preset device profiles for entry-level (8GB), mid-range (32GB), flagship (128GB), and tablet (256GB) configurations, or build a custom partition table for MTK scatter files, Qualcomm partition.xml, or Samsung pit file generation. The visual bar chart shows your partition layout to scale, and warns you immediately if partitions exceed the total storage capacity.
The bitwise operations panel supports AND, OR, XOR, NAND, NOR, XNOR, NOT, left shift (LSH), right shift (RSH), rotate left (ROL), and rotate right (ROR). Results are displayed in decimal, hexadecimal, binary, and octal simultaneously. This is essential for flag manipulation, bitmask creation, hardware register configuration, and GPIO pin state management in embedded firmware development.
So, Programmer Calculator tool helps with binary, decimal, and hexadecimal number systems along with bitwise operations, making it useful for developers and students. It improves coding accuracy and speed. You can also use it with Engineering Unit Conversion online, and Battery Life Calculator tool, and Download Time Calculator online for a complete set of tools.
