Worked check: 5 m = 16.40 ft (5 × 3.28084 = 16.4042); 10 miles = 16.09 km (10 × 1.60934 = 16.0934). Displayed values are rounded for readability — the full-precision value is used for the next conversion, not the rounded display.
Try an example: 5 metres → 16.40 feet
Length is the measurement we use most, and it is also the one that causes the most confusion, because the world uses two systems at once. Recipes, maps, road signs, clothing sizes, property listings and DIY plans all mix metres with feet, kilometres with miles, and centimetres with inches. The Length Converter from FistHost ends that confusion in one click: type a value in any unit, and it instantly shows the same length in metres, kilometres, centimetres, millimetres, miles, yards, feet and inches, so you never have to guess or reach for a calculator again.
The confusion is real because the units are close enough to mislead but far enough apart to matter. A metre is a little longer than a yard, a mile is a little longer than a kilometre and a half, and an inch is a little longer than two and a half centimetres. Guessing that they are equal is wrong by enough to ruin a cut of timber, a dress size or a running time. This converter uses the exact standard factors, shows the result two ways at once, and includes a table of common values, so you can check a conversion in seconds and trust it.
The converter is a single-purpose tool, which is exactly what makes it fast. You enter a value, pick the unit it is in, and the tool converts it to every other unit instantly, in both directions. There is no second form to fill in, no button to press and no page to reload. Change the value and every result updates at once, so you can test a whole range of numbers in a few seconds, for example a list of heights, a set of room sizes, or the distances on a running route.
Behind the scenes, every conversion goes through metres, which is the base unit of length in the metric system. The tool first converts your value into metres, then converts those metres into each of the other units. That single-step-through-metres design keeps every conversion consistent, so converting miles to kilometres and back again returns the same number you started with, apart from rounding. The factors are the standard ones used in science, trade and navigation, so the answers match the ones a surveyor, a map or a textbook would give.
The metric units are built on tens, which is why they are easy to work with. One kilometre is 1,000 metres, one metre is 100 centimetres, and one centimetre is 10 millimetres. A millimetre is the smallest unit most people use, for screws, paper thickness and small parts. A centimetre is the everyday unit for body measurements, clothing and small objects. A metre is the unit for rooms, furniture and people. A kilometre is the unit for roads, runs and journeys.
The imperial units come from older measures, and their factors are exact by definition. One inch is 2.54 cm exactly, which is the definition that ties the two systems together. One foot is 12 inches, one yard is 3 feet, or 0.9144 m, and one mile is 1,760 yards, or 1.60934 km. The key conversions to remember are 1 m = 3.28084 ft, 1 inch = 2.54 cm exactly, 1 mile = 1.60934 km, and 1 yard = 0.9144 m. Those four factors cover almost every length conversion you will ever need, from a person's height to the distance between two cities.
Here is the worked check the converter is built around, so you can follow the maths yourself. Take 5 metres and convert it to feet. The factor is 1 m = 3.28084 ft, so the calculation is 5 x 3.28084 = 16.4042 ft, which the tool shows as 16.40 ft. That is the whole check: multiply the metres by 3.28084, and the answer is the length in feet. A person who is 1.8 metres tall is 1.8 x 3.28084, or about 5.91 ft, which is 5 ft 11 in.
Now take 10 miles and convert it to kilometres. The factor is 1 mile = 1.60934 km, so the calculation is 10 x 1.60934 = 16.0934 km, which the tool shows as 16.09 km. That is the famous marathon check in reverse: a 10-mile run is just over 16 kilometres, and a 5-kilometre race is 5 / 1.60934, or about 3.11 miles. Try your own numbers and watch the pattern: a kilometre is always a little more than six tenths of a mile, and a mile is always a little more than one and a half kilometres.
Your result shows the converted length in every unit at once, so you can read the one you need without converting again. The main result is shown in large type, and the full table below it lists the same length in metres, kilometres, centimetres, millimetres, miles, yards, feet and inches. That table is useful when you are comparing two things in different units, for example a European recipe that gives a length in centimetres and an American pattern that gives it in inches, or a property listing in square feet and a floor plan in square metres.
Travel is the most common use. Road signs in the United States are in miles, while most of the world uses kilometres, so a driver abroad needs to know that 60 mph is about 97 km/h in speed and that a 100-mile journey is about 161 kilometres. Runners train in kilometres and race in miles, or the other way round, and a pace per mile means something different from a pace per kilometre. A 5-kilometre run is 3.11 miles, a 10-kilometre run is 6.21 miles, and a marathon is 42.195 km, or 26.22 miles.
Here is the honest label. Displayed values are rounded, and the tool says the full-precision value is used for the next conversion, not the rounded display. That matters when you chain conversions together. If you convert 5 metres to feet and see 16.40 ft, then convert 16.40 ft back to metres, you get 4.999 metres, not 5, because the 16.40 was rounded from 16.4042. The converter avoids that error by keeping the full-precision value behind the display and using it for every further conversion, so a chain of conversions stays accurate even though each displayed step is rounded to two decimal places.
Length is only one kind of measurement, and the same free calculators can convert the rest. If you need to convert kilograms to pounds or stones to kilograms, the weight converter does it instantly, two ways, with the same rounding rule and a common-values table. If your measurement is in another kind of unit altogether, from temperature to volume to speed, the unit converter covers the full range in one place. And if your length comes out as a fraction, for example 3 and 3/4 inches, the fraction calculator adds, subtracts and simplifies it without a decimal.

How many feet is 5 metres? 5 m = 16.40 ft, because 1 m = 3.28084 ft, so 5 x 3.28084 = 16.4042 ft.
How many kilometres is 10 miles? 10 miles = 16.09 km, because 1 mile = 1.60934 km, so 10 x 1.60934 = 16.0934 km.
Why does converting back give a slightly different number? Because displayed values are rounded, and the tool uses the full-precision value for the next conversion, not the rounded display, so the chain stays accurate.
