Instant Unit Calc
Read full descriptionHide full description
Simple Calculator combines a calculator and a unit converter in one app -- see your result converted into other units as you type, no switching required. Key features: - Handles complex expressions with parentheses, not just the four basic operations - An always-visible conversion panel across 5 categories: length, weight, volume, area, and temperature - Mixed-unit math like "2 cm + 3 kg" -- results are kept per unit instead of forcing a wrong conversion - Real dimensional analysis: "3 m × 4 m = 12 m²" -- multiplying and dividing changes the unit correctly - Cross-category multiplication/division shows a synthesized unit, like "10 mL ÷ 2 kg = 5 mL/kg" - Define your own custom units, like "1 gold coin = 17 silver coins, 1 silver coin = 23 copper coins" - Three themes: Light, Dark, and follow system setting - A focused, uncluttered interface -- no extra features to get in your way
