This page provides conversion factors and formulas for conversion of length expressed in inches to other units - micrometer, millimeter, centimeter, decimeter, meter, thou, foot, yard, mile, etc.
How to convert units:
In order to covert a measurement in inches to one of the units listed in the table below, simply multiply the length
value in inches by the conversion factor value listed in the corresponding row. Alternatively, use the formula provided
in the rightmost column.
In a situation where a direct conversion factor is not available, the following general unit conversion approach can be used.
Let's say, we have a value Lu1 expressed in one unit and would like to convert it to another unit -
Lu2. We also know the basic correlation between the units: Bu1 is equal to Bu2.
Then Lu2 can be calculated as:
Lu2 = Lu1 × Bu2 ÷ Bu1
For example:
We have Lin = 5 in and would like to find an equivalent in centimeters - Lcm.
The correlation between units is: 1 inch is equal to 2.54 centimeters, which means: Bin = 1 in and
Bcm = 2.54 cm
Using the formula listed above, we can find the length in centimeters:
Lcm = 5 in × 2.54 cm ÷ 1 in = 12.7 cm
Inch conversion factors and formulas:
| To convert inch to: | Multiply by*: | Formula: |
|---|---|---|
| centimeter (cm) | 2.54 | Lcm = Lin × 2.54 |
| decimeter (dm) | 0.254 | Ldm = Lin × 0.254 |
| foot (ft) | 0.0833333333333333 | Lft = Lin ÷ 12 |
| kilometer (km) | 2.54×10-5 | Lkm = Lin × 2.54×10-5 |
| meter (m) | 0.0254 | Lm = Lin × 0.0254 |
| micrometer (µm) | 25400 | Lµm = Lin × 25400 |
| micron | 25400 | Lµm = Lin × 25400 |
| mil | 1000 | Lmil = Lin × 1000 |
| mile (mi) | 1.57828282828283×10-5 | Lmi = Lin ÷ 63360 |
| millimeter (mm) | 25.4 | Lmm = Lin × 25.4 |
| nanometer (nm) | 2.54×107 | Lnm = Lin × 2.54×107 |
| nautical mile (NM) | 1.37149028077754×10-5 | Lnmi = Lin × 0.0254 ÷ 1852 |
| thou | 1000 | Lthou = Lin × 1000 |
| yard (yd) | 0.0277777777777778 | Lyd = Lin ÷ 36 |
