Education & Everyday Tools

From classroom help to restaurant checks, these tools cover common everyday calculations. Find your age in days and your age on other planets (Mercury, Venus, Mars, and more). Convert clothing and shoe sizes between US, UK, and EU when shopping abroad or online. Calculate your GPA from letter grades and credits, or see what grade you need to hit a target. Measure reading or typing speed in words per minute, or estimate how long it takes to read or type a piece of text. Split the bill and calculate tip and per-person amount for dinners and group outings. Every tool runs in your browser—no signup, no data stored.

We keep things simple: enter your numbers, get instant results, and use Example or Reset to try different scenarios. Size conversions use common charts (brands vary); GPA uses a standard 4.0 scale. These tools are for quick estimates and education—for official grades or tax records, use your institution or receipts.
