Feet to Inches+KM Converter (All Length Units)

Feet to Inches & Kilometers – Dual Range Conversion

Core idea: Inches zoom in (small-scale detail) while kilometers zoom out (large-scale distance). Both derive exactly from feet: 1 ft = 12 in = 0.0003048 km.

Formulas

• in = feet × 12
• km = feet × 0.0003048
• Reverse: feet = inches ÷ 12 = km ÷ 0.0003048
• Link: km = inches × 0.0000254 (since 1 in = 0.0254 m)

Quick Values

Worked Example

Example: 6 ft → inches = 6 × 12 = 72 in; km = 6 × 0.0003048 = 0.0018288 km. Cross-check: 72 in × 0.0000254 = 0.0018288 km.

Where Used

• Engineering sketches (inches) vs. geographic mapping (kilometers).
• Outdoor trail signage converting localized footing to regional distance.
• Education: contrasting micro (in) and macro (km) scales from one base.

Accuracy & Tips

• Factors exact (defined through the international foot & meter).
• Mental: 1 ft ≈ 0.0003 km (slight underestimate).
• Large totals: sum feet → km directly; avoid converting to inches first (reduces rounding steps).

More Examples

FAQ

• Why so many decimals in km? Feet are much smaller than kilometers; precision preserves accuracy.
• Best rounding? Use 2 decimals for inches, 6+ for km in small spans.
• Quick check? km × 3280.84 should return original feet (inverse).
