Length Conversion Definition

If you need to convert inches to feet, centimeters to miles or meters to picometers, our completely free length conversion calculator can help! It’s fast, simple and just as exact as you need it to be. Just enter the length of whatever you need to measure, choose the measurement you are currently using, pick how specific you need your calculations to be and the calculator will do the rest. This calculator is perfect for household tasks, translating measurements, elementary school math, and much more.

“Length”

In the length field on the calculator, enter the length of the item you are measuring. You can use whole numbers or decimals.

“Unit”

In the unit field of the calculator, choose the units you are currently using from the drop-down menu. If you live in the United States, you are likely using inches or feet. The calculator has thirty-one different options, including light years, rods, picas, links, and survey miles, so no matter what unit of measurement you find yourself using, the calculator can help.

“To”

In the to field, choose the unit of measurement you want your original measurement to be converted to from the drop-down menu. The same selection of thirty-one options, including gigameters, fathoms, and nautical miles, that you saw in the unit field is also available in the to field, so you can choose almost any combination imaginable.

“Precision (decimal places)”

In the precision field, choose the number of decimal places you want your answer to go to. If you would like a highly precise measurement, you will want more decimal places in order to be exact. If you are just looking for a general idea or are not overly concerned with precision, two decimal places should be suitable. The calculator offers from two to twelve decimal places in increments of two to serve whatever precision needs you may have.

When you have entered your measurement and made your selections, click the “calculate” button at the bottom of the calculator. The calculator will then generate the conversion you wanted to the level of precision you selected. If you made a mistake or would like to convert another length measurement, click the “back” button under your answer.

Whether you are working on a complex construction project (check out the construction calculator section) of just want to know how many links are in a furlong, this calculator can help you with all of your length conversion needs.
