NTS to GPS Converter: Turn Any NTS Grid Reference into Coordinates

NTS grid references show up across BC land records — mining claims, forestry cutblocks, pipeline rights-of-way — but they don't mean much without a map or a converter. This guide walks through the NTS format, where it appears in BC, and how to get latitude and longitude from any NTS reference in seconds using Township Canada.

What Is an NTS Grid Reference?

The National Topographic System (NTS) divides Canada into a hierarchy of map sheets, working from the broadest to the most precise:

1. Series — A number identifying a large map block (e.g., 93)
2. Area — A letter subdividing the series block (e.g., P)
3. Sheet — A number from 1 to 16 identifying a specific 1:50,000 scale map sheet (e.g., 8)
4. Block — A letter from A to L subdividing the sheet (e.g., F)
5. Unit — A number from 1 to 100 within the block (e.g., 2)
6. Quarter Unit — A letter from A to D (SW, SE, NE, NW) for the finest subdivision (e.g., A)

A full reference looks like: A-2-F/93-P-8

Reading that: Quarter Unit A, Unit 2, Block F, within map sheet 93-P-8. That pinpoints a location in the Peace River region of northeast BC — approximately 55.86°N, 120.68°W.

NTS references are written with the fine detail first and the broad map sheet last, separated by a slash. If you see a string like 93-P-8 alone, that's just the map sheet — you need the block and unit to get a precise point.

Where NTS Appears in BC

NTS is the standard location system for several industries operating in British Columbia:

• Mining claims — BC's mineral tenure system uses NTS grid references to define claim boundaries, particularly in northern and central BC
• Forestry — Timber sale licences and cutting permits in the northern interior reference NTS blocks
• Oil and gas — Petroleum and natural gas tenure in northeast BC uses NTS, though DLS is also common in that region
• Environmental assessments — Project area descriptions in northern BC often include NTS references alongside or instead of legal land descriptions

If you work with land records from the BC Oil and Gas Commission, the BC Ministry of Energy, or Mines Digital Services (MDS), you'll encounter NTS references regularly.

How to Convert NTS to GPS with Township Canada

Township Canada reads NTS grid references and returns the centre-point coordinates for any valid reference. Here's how to do it:

Step 1 — Enter the NTS reference Open the Township Canada converter and type your reference into the search field. Use the standard format with a slash between the unit portion and the map sheet: A-2-F/93-P-8.

Step 2 — Review the result The map centres on the converted location and displays the latitude and longitude. For A-2-F/93-P-8, you'll land in the Peace River country near Fort St. John at roughly 55.86°N, 120.68°W. The result panel shows the full parsed breakdown so you can verify each component was read correctly.

Step 3 — Export or navigate Copy the coordinates directly, export to KML for use in GIS software, or open in Google Maps or your GPS device. The guides on batch conversion cover exporting multiple references at once.

Step 4 — Batch convert a list If you have dozens of NTS references from a tenure database or field report, paste the full list into the batch tool. Business plan users can upload a CSV and download results in one pass.

Common Mistakes When Working with NTS

Confusing NTS with DLS in northeast BC. The Peace River region is unusual — it uses both systems. Agricultural land and many road addresses follow DLS (Dominion Land Survey), while resource tenures use NTS. If your reference looks like Twp 84 Rge 14 W6M, that's DLS, not NTS. See the DLS to GPS converter for that format.

Wrong map sheet number. Sheet numbers run 1 to 16 within each lettered area. Entering 93-P-18 instead of 93-P-8 won't return a valid result — sheet 18 doesn't exist. Double-check the number against the original document.

Reversed block and unit order. The block letter comes before the unit number in NTS notation (F/2, not 2/F). Documents that list these in plain text sometimes swap the order accidentally.

Dropping the quarter unit. Some older records omit the quarter unit and give only 2-F/93-P-8. That's valid — it returns the centre of the full unit rather than a quarter. Be aware the area covered is four times larger.
