The default is 1 ha; the field accepts nonnegative numbers.<\/li>\n<li>Read the converted area under <strong>Square Kilometers<\/strong>. The result is labeled km\u00b2.<\/li>\n<li>To check the result yourself, divide the hectare value by 100. For example, 250 ha \u00f7 100 = 2.5 km\u00b2.<\/li>\n<\/ol>\n<p>Use a decimal value when the area is not a whole number of hectares. For example, 12.5 ha converts to 0.125 km\u00b2. If your source measurement is already in square kilometers, this calculator runs in the opposite direction: multiply that value by 100 to find hectares.<\/p>\n<h2>Understanding hectares and square kilometers<\/h2>\n<p>A hectare is an area of 10,000 square meters. It is often used for farms, forests, parks, and individual land parcels. A square kilometer is an area of 1,000,000 square meters and is often more convenient for larger regions. Because 1,000,000 \u00f7 10,000 = 100, one square kilometer equals exactly 100 hectares.<\/p>\n<p>Converting units changes how an area is written, not how much ground it covers. A 300 ha site is also a 3 km\u00b2 site. Square kilometers can make regional figures easier to compare without changing the underlying measurement. Hectares may be easier to read when those same figures are broken down into smaller plots.<\/p>\n<p>The square in km\u00b2 matters: it describes area, not distance. A square measuring 1 km along each side covers 1 km\u00b2, or 100 ha. That example explains the unit\u2019s size; the land being measured does not need to be square. Likewise, a hectare describes an area, not a particular boundary shape.<\/p>\n<h2>Practical notes and limitations<\/h2>\n<ul>\n<li><strong>This is an exact unit conversion.<\/strong> The factor of 0.01 does not introduce measurement uncertainty. However, a converted figure is only as reliable as the hectare value entered.<\/li>\n<li><strong>Displayed results are rounded.<\/strong> The calculator rounds its square-kilometer result to six decimal places. For very small areas, keep the original hectare measurement if you need more detail than the displayed result provides.<\/li>\n<li><strong>Enter area, not length.<\/strong> A boundary length in kilometers cannot be converted to hectares without information about the shape or dimensions of the land.<\/li>\n<li><strong>Check what your source measures.<\/strong> A reported land area may be a surveyed parcel area, a mapped area, or an estimate. This converter changes its unit but does not resolve differences between those measurements.<\/li>\n<\/ul>\n<p>If you are comparing figures from several sources, convert them all to the same area unit before adding or comparing them. For other land-area units, use the <a href=\"https:\/\/wpcalc.com\/en\/converters\/land-area\/\">Land Area Unit converter<\/a>. If a source gives acres, the <a href=\"https:\/\/wpcalc.com\/en\/converters\/acres-to-square-meters\/\">Acres to Square Meters converter<\/a> can help put that figure into metric units.<\/p>\n<h2>Hectares to square kilometers reference<\/h2>\n<table>\n<thead>\n<tr>\n<th>Hectares (ha)<\/th>\n<th>Square kilometers (km\u00b2)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>1<\/td>\n<td>0.01<\/td>\n<\/tr>\n<tr>\n<td>10<\/td>\n<td>0.1<\/td>\n<\/tr>\n<tr>\n<td>25<\/td>\n<td>0.25<\/td>\n<\/tr>\n<tr>\n<td>50<\/td>\n<td>0.5<\/td>\n<\/tr>\n<tr>\n<td>100<\/td>\n<td>1<\/td>\n<\/tr>\n<tr>\n<td>250<\/td>\n<td>2.5<\/td>\n<\/tr>\n<tr>\n<td>1,000<\/td>\n<td>10<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Convert an area from hectares to square kilometers.
