Binary to Decimal Converter
Convert binary numbers to decimal instantly. Simple enough for a 5-year-old, educational for everyone!
Enter a binary number (only 0s and 1s) in the field above. Each digit is called a “bit”.
The decimal equivalent will appear here after conversion. Decimal is the number system we use every day (0-9).
Conversion Result
1×128 + 1×64 + 0×32 + 1×16 + 1×8 + 0×4 + 1×2 + 0×1 = 128 + 64 + 16 + 8 + 2 = 218
How Binary Works
Conversion Steps
Write Binary
Start with a binary number (e.g., 1010)
Assign Powers
Assign powers of 2 from right to left (2⁰, 2¹, 2², …)
Multiply Bits
Multiply each bit by its corresponding power of 2
Sum Values
Add up all the values to get the decimal equivalent
Digital Access as a Fundamental Human Right
In our increasingly digital world, access to technology and digital literacy has become a fundamental human right. While not explicitly mentioned in the original 1948 Universal Declaration of Human Rights, the evolution of our society has elevated digital access to a necessity for full participation in modern life.
The Foundation of Digital Rights
Article 19 of the Universal Declaration establishes the right to freedom of opinion and expression. In the 21st century, this right extends to digital spaces and requires access to technology. Tools like this binary converter represent more than just a utility – they embody the democratization of technical knowledge that was once accessible only to specialists.
Barriers to Digital Inclusion
Over 3 billion people worldwide still lack internet access, creating a digital divide with significant consequences:
- Limited access to educational resources and online learning
- Reduced economic opportunities in an increasingly digital economy
- Exclusion from digital government services and civic participation
- Difficulty accessing healthcare information and telemedicine
- Social isolation in a digitally connected world
Digital Literacy as an Equalizer
Understanding fundamental computing concepts like binary numbers helps bridge the knowledge gap by:
- Demystifying technology that powers our world
- Building foundational knowledge for STEM education
- Empowering individuals to understand data privacy concepts
- Enabling critical thinking about technology’s role in society
- Creating pathways to technology careers
Designing for Universal Access
True digital inclusion requires tools accessible to everyone, regardless of age or technical background. This converter embodies accessibility principles:
- Simple interface usable by children and adults alike
- Visual explanations of abstract concepts
- Responsive design that works on any device
- Educational content integrated with functionality
- Immediate feedback to reinforce learning
The Path Forward
As we move toward an increasingly digital future, ensuring universal access to technology and digital literacy becomes critical. Free educational tools that make technical concepts approachable represent a step toward fulfilling the promise of universal human rights in the digital age.
Every binary conversion represents not just a mathematical operation, but the exercise of one’s right to understand the digital world we inhabit.
