Border and coastline measurements in the Geography section are incomplete as they neglect the coastline length of Northern Ireland and of all the islands other than Great Britain itself, as stated in the reference source link named "UK coastline".

Suggested replacement:

Northern Ireland shares a {{Convert|499|km|mi|0|adj=on|order=flip}} land boundary with the Republic of Ireland<ref name="factbook" /> and has a {{Convert|650|km|mi|0|adj=on|order=flip}} coastline.<ref name="NI coastline">{{Cite web |title=Northern Ireland Coastal and Marine Forum |url=https://library2.nics.gov.uk/pdf/dard/2014/EEUD.pdf |archive-url=https://web.archive.org/web/20241123094028/https://library2.nics.gov.uk/pdf/dard/2014/EEUD.pdf |archive-date=23 November 2024 |access-date=13 March 2025 |publisher=Northern Ireland Costal and Marine Forum}}</ref> The length of coastline of Great Britain plus its principal islands is about {{Convert|31368|km|mi|0|order=flip}} long, with the coastline of the main island Great Britain being {{Convert|17820|km|mi|0|order=flip}} of that,<ref name="UK coastline">{{Cite web |last=Darkes |first=Giles |date=January 2008 |title=How long is the UK coastline? |url=http://www.cartography.org.uk/default.asp?contentID=749 |archive-url=https://web.archive.org/web/20120522042745/http://www.cartography.org.uk/default.asp?contentID=749 |archive-date=22 May 2012 |access-date=24 January 2015 |publisher=The [[British Cartographic Society]]}}</ref> though measurements can vary greatly due to the [[coastline paradox]].<ref>{{Cite web |last=Weiner |first=Sophie |date=3 March 2018 |title=Why it's Impossible to Accurately Measure a Coastline |url=https://www.popularmechanics.com/science/environment/a19068718/why-its-impossible-to-accurately-measure-a-coastline/ |access-date=29 June 2024 |website=Popular Mechanics |language=en-US |archive-date=29 June 2024 |archive-url=https://web.archive.org/web/20240629025825/https://www.popularmechanics.com/science/environment/a19068718/why-its-impossible-to-accurately-measure-a-coastline/ |url-status=live }}</ref> It is connected to continental Europe by the [[Channel Tunnel]], which at {{Convert|50|km|mi|0|order=flip}} ({{Convert|38|km|mi|0|order=flip}} underwater) is the longest underwater tunnel in the world.<ref>{{Cite web |title=The Channel Tunnel |url=http://www.eurotunnel.com/ukcP3Main/ukcCorporate/ukcTunnelInfrastructure/ukcInfrastructure |archive-url=https://web.archive.org/web/20101218114514/http://www.eurotunnel.com/ukcP3Main/ukcCorporate/ukcTunnelInfrastructure/ukcInfrastructure |archive-date=18 December 2010 |access-date=8 March 2015 |publisher=Eurotunnel}}</ref>
