How to use this calculator
- Enter the known values in the units shown. Results update as you type.
- Where results are editable, change one to solve backwards. Lock a value to hold it fixed.
- Use the worked example to check the method. Reset restores the starting fields.

Formula and method
One international yard equals three feet, 36 inches or 0.9144 m. Multiply the yard count by 0.9144 to express it in meters.
Feet = yards × 3; inches = yards × 36; meters = yards × 0.9144
Worked example
Enter these known values and leave the other values blank.

Assumptions and limitations
- International units use exactly 25.4 mm per inch, 0.3048 m per foot, 0.9144 m per yard and 1,609.344 m per statute mile. A nautical mile is exactly 1,852 m.
- Every field describes the same length. Zero and signed values are supported for directed measurements; a negative result does not describe a physical size. Display rounding does not increase the precision of the original measurement.
- In a compound feet/inches field, use a colon: 1:6 means one foot six inches. Decimal 1.6 feet is one foot 7.2 inches. Read the selected unit when editing a flexible field.
- The optional legacy US survey foot is exactly 1200/3937 m. It differs from the international foot; use it only to interpret data explicitly expressed in that legacy unit.
- The optional copper-foil scale retains the nominal convention 1 oz/ft² = 35 µm of thickness. It is not a fluid ounce, an exact mass-to-length identity, or a guarantee of finished PCB copper thickness.
Common questions
Can I use this to convert square yards or cubic yards?
No. These fields represent length. Area uses the square of the length factor, and volume uses its cube; use an area or volume converter for those quantities.
Can I work backward from a result?
Yes. Enter the known length in any editable field to update the other representations. Check the selected unit first, especially in the flexible comparison fields.
Why does changing a unit change the number?
The length stays the same while the size of the unit changes. A longer unit needs a smaller number of units to represent the same distance.

The optional legacy US survey foot uses exactly 1200/3937 meters, replacing the rounded reference factor. Ordinary international feet remain exactly 0.3048 meters.
