Formula
Total Inches = (Feet Ă— 12) + Inches
Decimal Feet = Total Inches Ă· 12
Metric conversions rely on the exact factors: 1 inch = 2.54 cm, 1 foot = 0.3048 m.
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Mixed feet-and-inch measurements are common across carpentry, interior design, construction, and everyday height tracking. This calculator simplifies the process by delivering all equivalent values at once.
Because the imperial system separates feet and inches, many downstream tasks—from ordering materials to entering data into spreadsheets—require decimal or metric versions. By translating the measurement instantly, you avoid manual arithmetic and reduce transcription errors.
Use the results to resize blueprints, compare athletic stats, or convert DIY plans into metric specifications.
Frequently Asked Questions
Can I enter fractional inches?
Yes. Enter them as decimals (for example, 8.5 inches). The calculator handles the conversion automatically.
Does the calculator accept negative values?
No. Distance measurements use non-negative numbers. If you see a negative result, double-check the input values.
How precise are the metric conversions?
The tool uses exact conversion factors (1 in = 2.54 cm, 1 ft = 0.3048 m). Results are rounded for readability but retain full precision internally.
Can I copy the totals into another program?
Absolutely. Highlight any output and copy it into your spreadsheet, CAD software, or project notes.
