How to Convert Feet to Inches
One foot contains exactly 12 inches. Multiply the value in feet by 12 to obtain inches.
feet × 12 = inches
The calculator multiplies your input by 12. The displayed result is rounded for readability; keep additional decimal places when continuing a calculation. Round the final answer to a precision that matches the original measurement rather than adding apparent accuracy to a rough estimate.
A worked example
A 7.5-foot wall segment is 7.5 × 12 = 90 inches. If your note says 7 feet 6 inches, convert the feet first and then add the remaining inches: 84 + 6 = 90.
Using the result for a floor plan
This conversion helps compare room dimensions with furniture or cabinetry specifications given in inches. Convert the entire mixed measurement, including any additional inches. Do not type 7.6 to represent 7 feet 6 inches; 7.6 is a decimal number of feet.
Record the original value and unit beside the converted value when sharing notes. This makes it easier to trace a mistake and avoids confusing a converted measurement with a new on-site measurement. Conversion changes the unit used to describe a quantity; it does not improve the accuracy of the quantity you started with.
Common Feet to Inches Values
1 foot in inches
1 foot equals approximately 12 inches. This is the base relationship: each foot corresponds to approximately 12 inches. Keep the full conversion factor when multiplying a larger measurement.
10 feet in inches
10 feet equals approximately 120 inches. To check this value, multiply 10 by 12. Scale from the full factor rather than multiplying a rounded one-unit result.
100 feet in inches
100 feet equals approximately 1200 inches. This result represents a linear distance. A 100-square-foot floor area cannot be converted with the same multiplier; area needs a squared conversion factor.
Feet to Inches FAQ
Is this converter free to use?
Yes. No registration, subscription, or credit is required. Enter a non-negative value and read the result immediately. The calculation takes place in your browser, and you can also use the formula and reference table without running the calculator.
Why does my result have several decimal places?
Many conversions do not produce a whole number. The calculator displays up to six decimal places. Preserve enough precision for intermediate calculations, then round once at the end. A long decimal does not mean your original physical measurement was equally precise.
Can I enter a decimal measurement?
Yes. Enter a decimal number in the source unit. Convert a written fraction into a decimal first: one half is 0.5 and one quarter is 0.25. Do not enter mixed-unit notation into a single numeric field; first express the complete measurement in one unit.
Does changing the unit change the drawing scale?
No. A unit conversion expresses the same quantity in a different system. Drawing scale is the relationship between a length on a drawing and the real-world length. Check that relationship separately before measuring a printout, tracing an image, or exporting linework.
Can I use a length factor for floor area?
No. Area conversions use squared length relationships, so their factors differ from ordinary length conversions. Choose the appropriate area converter for square feet, square meters, or acres. Keep wall lengths and floor areas labeled separately throughout your project.
