Land here is advertised in one unit, registered in another and farmed in a third. Enter a figure in the unit you have — jutro, lanac, hvat, dunum, ar, hectare or acre — and read it in every other unit at once. Handy when a listing says "three jutra" and the cadastre says square metres.

How it works
Every unit is defined by its size in square metres and conversions run through that base, so results are consistent in both directions. The metric units are exact by definition: 1 ar is 100 m², 1 hectare is 10,000 m² or 100 ari, 1 km² is 100 hectares.
The cadastral units come from the Austro-Hungarian survey and are derived rather than rounded. One fathom (hvat) is 1.8964838 m, so one square fathom is 3.596652 m². A katastarsko jutro is 1,600 square fathoms, which works out to 5,754.64 m² — a little over half a hectare. Lanac is listed at the same size, because in Vojvodina it is used as another name for the katastarsko jutro.
The dunum (dulum) is an Ottoman-era measure, standardised at 1,000 m², still heard in the south and across Bosnia. The acre is included because it turns up in foreign documents: 4,046.856 m², roughly 0.7 of a jutro. Official land records use m² and hectares, so treat the old units as everyday speech that needs translating rather than as legal measures.
Practical examples
One jutro in modern units
1 katastarsko jutro is 5,754.64 m², which is 0.575 hectares or 57.55 ari. It is why "a jutro of land" and "half a hectare" are almost the same thing in conversation.
A three-lanac plot
Three lanca is 17,263.9 m², or about 1.73 hectares. Enter 3 in lanac and the hectare row answers the question a listing usually leaves open.
Ten jutara of farmland
10 jutara is 5.75 hectares — useful when a subsidy form or a machinery rate is quoted per hectare but the family talks in jutra.
Square fathoms on an old deed
An older document listing 400 kvadratnih hvati means 1,438.66 m², a quarter of a jutro. The tool converts it without you having to remember the fathom.
Frequently asked questions
How many square metres is one katastarsko jutro?
5,754.64 m². The figure comes from 1,600 square fathoms of 3.596652 m² each, which is why it is not a round number — it predates the metric system.
Is a lanac the same as a jutro?
In Vojvodina, yes — the words are used interchangeably for the same cadastral unit, and the tool treats them as equal. Elsewhere you may meet locally different sizes, so check against a document before it matters financially.
How many ari are in a jutro?
About 57.55, since one ar is 100 m². A jutro is a little more than half a hectare, which is the mental shortcut most people use.
What is an ar and how does it differ from an acre?
An ar is metric — 100 m², the unit gardens and building plots are advertised in. An acre is imperial at 4,046.856 m², about 40 times larger. The similar name is a coincidence and a frequent source of confusion.
What is a dunum?
An Ottoman-era land measure, standardised at 1,000 m² — ten ari. It is still common in everyday speech in the south of the country and across the region, though it never appears in Serbian land records.
Why is the jutro figure not exactly 5,755 m²?
Because it is derived from the fathom rather than defined in metres. The rounded 5,755 m² you often see is a convenience; the tool uses 5,754.642 m² so repeated conversions do not drift.
Which unit will the land registry use?
Square metres, with hectares for larger parcels. Old units survive in classified ads and family conversation, so converting into m² is usually the first step in checking a listing against the cadastre.
How do I convert a plot given as 6 × 25 m?
Multiply first — that is 150 m² — then enter it here to see it in ari (1.5). For irregular shapes our area calculator handles the geometry.
Can I compare a price per ar with a price per hectare?
Yes: 1 hectare is 100 ari, so a price per ar multiplied by 100 gives the price per hectare. Convert the area first and the price comparison becomes straightforward arithmetic.
Does it handle very large or very small numbers?
Yes. Results are shown with up to six decimals and trailing zeros trimmed, so both a 40 m² garden strip and a 300-hectare estate read sensibly.
Is the decimal comma supported?
Yes. Both 2,5 and 2.5 mean two and a half, and pasted numbers with thousand separators are read correctly too.
Where should I check a disputed area?
The cadastre extract for the parcel is the only authoritative source. This tool converts units accurately, but it cannot tell you what a particular parcel actually measures.
