BCD to Decimal Conversion | Summary and Q&A
TL;DR
Learn how to convert a binary coded decimal into a decimal number by splitting it into groups of four, assigning values to each group, and adding them up.
Key Insights
- 👨💻 Binary coded decimal (BCD) values are split into groups of four for conversion to decimal.
- 🫦 Each group of four bits in BCD represents a decimal digit, with positions corresponding to values 8, 4, 2, and 1.
- 👥 Converting BCD to decimal involves summing the values of each group.
- 🥺 Leading zeros in BCD are not significant for conversion to decimal.
- #️⃣ BCD numbers can be converted to binary by converting each digit separately, but the resulting binary number may not be in the most efficient representation.
- 🆘 Regular practice with examples helps in mastering BCD to decimal conversion.
- ❓ The process of converting BCD to decimal is straightforward and accurate if the steps are followed correctly.

Questions & Answers
Q: How do you convert a binary coded decimal into a decimal number?
To convert a BCD into a decimal number, split it into groups of four. Assign values to each group based on the positions of the non-zero bits (8, 4, 2, 1). Add up the values for each group to get the decimal number.
Q: What does each group of four binary numbers in BCD represent?
Each group of four binary numbers in BCD represents a digit in a decimal number. The positions of the bits within the group correspond to the values 8, 4, 2, and 1 respectively.
Q: Are leading zeros significant in a BCD number?
Leading zeros in a BCD number are not significant. They can be omitted when converting the BCD to a decimal number as they do not contribute to the overall value.
Q: Can BCD numbers be converted directly into binary?
BCD numbers can be converted into binary by converting each BCD digit into a 4-bit binary number and combining them. However, the resulting binary number may not necessarily be in the most compact binary representation.
