🧮 Base Converter & Byte Calculator

📖 Online Base Converter: Instantly Convert Binary, Octal, Decimal, Hex – Essential Developer Tool

Base conversion is one of the most fundamental operations in computer science and daily development. The online base converter & byte calculator from ng.cc is completely free, requires no installation, and supports real-time conversion between binary, octal, decimal, and hexadecimal. It also includes byte/KB/MB/GB conversion and a simple calculator. All calculations happen locally in your browser – no data is sent to any server, ensuring your privacy.

🎯 Why Use a Base Converter?

Base conversion is indispensable in many scenarios:

• Bitwise programming: Bit operations (&, |, ^, <<, >>) in C/C++, Java, Python often require a binary view.
• Color codes: Hexadecimal colors in CSS (#FF5733) need conversion to RGB values.
• Permission settings: Linux/Unix file permissions use octal (e.g., 755, 644).
• Memory addresses: Debugging hex addresses require decimal understanding for size.
• Network protocols: IP and MAC address conversions.
• Data unit conversion: File sizes and memory capacities between B, KB, MB, GB, TB.

💡 How to Use This Tool?

🔹 Method 1: Decimal to Other Bases (Most Common)

1. Type any integer in the Enter Decimal Number field on the left.
2. The corresponding binary, octal, and hexadecimal results appear instantly on the right.
3. Byte unit conversion and bit count are automatically calculated below.

🔹 Method 2: Other Bases to Decimal

1. In the Input from Other Bases section, choose the corresponding base input box.
2. Enter a binary (e.g., 1010), octal (e.g., 755), or hexadecimal (e.g., 1A3F) value.
3. Click the → Decimal button. The result will populate the decimal input and trigger all conversions.

🔹 Method 3: Calculator & Conversion Linkage

1. Use the calculator buttons to enter an expression (e.g., 1024*1024).
2. Press = to evaluate. The result automatically fills the decimal input and updates all conversions.

❓ Frequently Asked Questions (FAQ)

Q1: What do the prefixes 0b, 0, and 0x mean?

These are common programming notations: 0b1010 means binary 10, 0755 means octal 755, 0x1A3F means hexadecimal 1A3F. This tool uses these standard formats so you can directly copy results into your code.

Q2: Does it support fractional base conversion?

This version focuses on integer conversion, the most common developer need. For fractional conversions, we recommend a scientific calculator.

Q3: What is the formula for byte conversion?

1 KB = 1024 B, 1 MB = 1024 KB, 1 GB = 1024 MB, 1 TB = 1024 GB. This tool uses binary prefixes (KiB, MiB displayed as decimal but values are binary-based).

Q4: Why is the binary representation sometimes very long?

Each binary digit represents only 0 or 1, so expressing the same value requires about 3.3 times more digits than decimal. For example, decimal 1024 is binary 10000000000 (11 bits). This is normal.

Q5: What is the maximum supported number?

Due to JavaScript's Number type limitations, this tool supports integers up to 9007199254740991 (2^53-1). Values beyond this may lose precision.
