3Conversion and material grid
Multiply linear feet by 0.3048 to get exact linear meters.
Multiply meters by 3.2808 when checking against imperial drawings.
Extra inches and cut allowances are converted before waste.
Trim work normally needs room for miters, scarf joints, and offcuts.

6Rounding rule table
| Rounding option | Best for | Formula used | Practical check |
|---|---|---|---|
| Exact converted length | Estimating or drawing review | Feet x 0.3048 | No ordering buffer beyond entered waste |
| Round to stock pieces | Trim, tube, bar, conduit sticks | Ceiling(required / stock meters) | Watch offcut layout if each segment must be continuous |
| Round to roll or reel length | Cable, rope, webbing, fabric rolls | Ceiling(required / roll meters) | Buy whole reels when suppliers do not split rolls |
| Round to metric package | Track, pipe, edging, imported trim | Ceiling(required / package meters) | Useful when drawings are imperial but product is metric |
| Largest applicable pack | Mixed supply planning | Largest of stock, roll, package | Prevents under-ordering when several package rules matter |

8Two practical tips
When a person is converting the measurement from an imperial drawing to metric order length, there may be a significant gap between the two length. The measured length refer to the distance that can be measured on the drawing. The ordered length is the total amount of material that a person has to order from a supplier.
The gap between these two lengths result from the fact that a person has to order additional length according to the cut and the amount of material that the supplier sells. A feet to linear meter calculator help to fill the gap between these two lengths by helping a person to convert the field measurement into the correct order length. Another reason that a person must account for in the calculation of the total length of material that is required for a project is for the loss of material that may occur during installation.
Why Measured Length Is Not the Same as Ordered Length
Loss of material may occur during the installation of a project due to the fact that each joint, miter, or other point of termination of the materials requires an additional length of material to be purchase. The feet to linear meter calculator allow a person to add allowance for each segment of material to account for such loss. In addition to provide allowances for material loss during installation, a person must also provide for the waste that may be create in the cutting of the materials.
This waste percentage is not to be determined at will by a person but is a calculation that ensure that a person will not run out of material during the project. The next factor that a person should consider when determining the length of material to order from suppliers is stock rounding. Once a person has determined the true length of material that is required for a project, it is necessary to round that length to the length of the stock from which the materials are available.
Most supplier offer materials in preset unit of stock. A feet to linear meter calculator handle the stock rounding for a person. Such a calculator will provide both the length of material that is needed and the length that will be order from the supplier.
The surplus of material that will result from the rounding of the true length of material to the length of available stock is the cost of ordering material from available supplier. Depending on the type of materials that are to be used in a project, a person must follow different rule in calculating the length of the materials that will be ordered. For instance, the length of fabric and upholstery may include allowances for the number of time that a pattern will be repeated in the area that is to be covered by the material.
Wood trim does not have to account for the number of times a pattern is repeat. Other materials, such as cable, require allowance for the length needed for the service loop and tails for the pull box at each end of the cable. The length of pipe should allow for the length of the fitting that will be used in installing the pipe.
Each type of material has its own allowance for waste that can be program into a feet to linear meter calculator. There are also reference table that can be used in determining the length of material that is needed. These reference tables include information about the lengths of stock material that is available in various supplier and the typical waste percentage that are introduced during the cutting of the materials into the length that are ordered.
These reference tables can be consulted before the use of a feet to linear meter calculator. Additionally, these tables provide information about the different type of projects and the different types of allowances that can be made for the rounding of material length. For example, the lengths of fence wire may have allowances for the length of the splices that are used to join the lengths of wire.
Curtain track may not allow for these type of splices. These tables assist in determining if a person will require one long piece of material for a project or if there will be splices in the materials for that project. It is also important to consider that the length of material that is required for a project may differ from the drawing of the project.
The terrain in which a project is to be installed may not be as clear as depict in the drawing. The door swing that are to be used may not allow for the length of material that may be calculate from the drawing. There may be other reason that may require a reroute of the materials.
The spare meter field in a feet to linear meter calculator allow a person to account for these variable. A spare meter field allows for a more realistic estimate to be provide for the length of material that will be ordered. A person should follow a specific order when entering the length of a project into a feet to linear meter calculator.
A person should enter the length of the project. Then, the number of meters of material that will be lost during installation should be enter into the calculator. Following this step, the waste percentage can be enter into the calculator.
Finally, the order length should be round to the length of stock material that will be available from the supplier. If these step are followed in the wrong order, a person might hide the true length of material that will be needed for projects that have only one segment of the materials need. When using the calculator to determine the length of material that will be ordered for a project, a person will find that the software present to that person a series of breakdown card that show the length of each type of allowance and how each allowance contribute to the total length of the material that will be order for the project.
These breakdown cards make it easier for a person to present the calculation to their client or supplier. The value of using a feet to linear meter calculator is in the clarity of the tool regarding the gap between the length of the materials that are to be measure from the drawings to the length that will be order from the suppliers of the materials.
