## What is Unit Sharp?

Unit Sharp is a mental math trainer designed to build intuition for unit conversions.

Instead of relying on formulas or calculators, you learn to estimate values using scale, context, and real-world reasoning.

This is not a converter — it’s a skill.

HOW IT WORKS

• Estimate the answer to a conversion problem  
• Enter your guess using a simple keypad  
• Get instant feedback based on accuracy  
• Improve your intuition over time  

---

ACCURACY-BASED SCORING

Answers are graded by how close you are:

• Exact  
• Close  
• Ballpark  

Different categories have different precision standards. Scientific units require tighter accuracy, while others allow broader estimates.

Your session score reflects your average performance — consistency matters more than perfection.
