Frequently Asked Questions
Common questions about digital & technology calculators and tools
Q.Which number systems can I convert between on CalcPool?
CalcPool currently has 6 number system converters: Binary ↔ Decimal, Binary ↔ Hexadecimal, Binary ↔ Octal, Decimal ↔ Hexadecimal, Decimal ↔ Octal, and Hexadecimal ↔ Octal. All conversions are instant and show step-by-step working.
Q.Do the number converters show their working?
Yes. Every converter shows the full positional value breakdown. For example, converting binary 1010 to decimal shows: (1×2³) + (0×2²) + (1×2¹) + (0×2⁰) = 8 + 0 + 2 + 0 = 10.
Q.How does the Phone Life Thief Calculator work?
Enter your average daily screen time. The calculator multiplies this by your remaining life expectancy (based on WHO data for your region) to calculate the total years of conscious waking life you will spend on your phone if current habits continue. It also shows the breakdown by current age lost.
