📐 Conversion Formulas Used
All conversions use Meters (m) as the bridge unit.
Step 1 → Convert to meters: meters = input × factor_of_from_unit
Step 2 → Convert to target: result = meters ÷ factor_of_target_unit
Step 2 → Convert to target: result = meters ÷ factor_of_target_unit
🔬 Micro / Nano / Pico Scale Conversions
1 pm = 1 × 10⁻¹² m
1 nm = 1 × 10⁻⁹ m
1 µm = 1 × 10⁻⁶ m
Example: Convert 5 µm to nm
nm = 5 × 1000 = 5000 nm
Example: Convert 12000 nm to µm
µm = 12000 ÷ 1000 = 12 µm
📏 Medium & Large Unit Formulas
1 mm = 0.001 m
1 cm = 0.01 m
1 km = 1000 m
1 inch = 0.0254 m
1 foot = 0.3048 m
1 yard = 0.9144 m
1 mile = 1609.34 m
1 light year = 9.461 × 10¹⁵ m
Example: Convert 3 km to ft
m = 3 × 1000 = 3000 m
ft = 3000 ÷ 0.3048 = 9842.52 ft
ft = 3000 ÷ 0.3048 = 9842.52 ft
Example: Convert 600000000 nm to cm
m = 600000000 × 10⁻⁹ = 0.6 m
cm = 0.6 ÷ 0.01 = 60 cm
cm = 0.6 ÷ 0.01 = 60 cm
🌉 Why Meters?
Because every unit has a fixed mathematical relation with meters, accuracy is maintained even in extreme micro and astronomical scales.
⚙ Precision Method
Calculator performs exact floating arithmetic and scientific notation substitution without rounding shortcuts, preventing errors in micro/nano results.
