Frequently asked about the Everyday & Lifestyle
What's in the Lifestyle category?
15 calculators: GPA (4.0 or 10.0 scale), CGPA-to-percentage, exam grade needed for target, exam score predictor (with negative marking), tip + split bill, love-compatibility (fun), name numerology, age in days/hours/minutes, zodiac (Western + Chinese), wedding anniversary symbol, retirement countdown, carbon footprint, and water footprint.
Is the GPA calculator US or Indian?
Both — toggle between 4.0 scale (US) and 10.0 scale (India / CBSE / VTU). Paste grade:credit pairs, get cumulative GPA. The CGPA-to-Percentage calculator follows the standard ×9.5 rule for 10-point scales (VTU / Anna University use slightly different multipliers — verify with your institute).
How does the love compatibility calculator work?
It's a fun calculator, not science — it sums letter occurrences from 'LOVES' across both names and computes a percentage. Don't make life decisions from it.
Is name numerology real?
Numerology is a belief system, not science. We provide the Pythagorean numerology mapping (A=1, B=2, …, summed and reduced to a single digit) as a curiosity. Treat it as entertainment, not advice.
Is the carbon footprint accurate?
Rough order of magnitude. Inputs are annual km driven, short and long flights, and diet category. Output is tonnes CO₂/year. Actual values depend on your car's efficiency, electricity grid mix, food sourcing, etc. Use it for awareness, not regulatory reporting.
Anniversary symbol meanings?
Year 1 = paper, 5 = wood, 10 = tin, 25 = silver, 50 = gold, 60 = diamond, 75 = platinum. The Wedding Anniversary calculator shows your number and matching symbol.
