GPS Coordinate Converter
Converts GPS coordinates between decimal degrees and degrees-minutes-seconds (DMS) format
Updated 26 June 2026 · Live
What this tool does
Converts GPS coordinates between decimal degrees and degrees-minutes-seconds (DMS) format.
GPS Coordinate Converter — choose a direction, then enter {degrees}, {minutes}, {seconds} and {hemisphere} (for DMS → Decimal) or {decimal_degrees} and {axis} (for Decimal → DMS) to get {result}.

How the gps coordinate converter works
Converts between decimal degrees, DMS, and UTM coordinate formats. The calculator takes your dimensions and supplier rates, applies a standard Australian trade formula, and returns a quantity with an indicative cost. Every figure is an estimate — site conditions always move the final number.
Typical Australian surveying and mapping wastage
Setting-out errors do not waste material at the survey stage but compound through every following trade — a 10 mm error at first fix becomes a 50 mm problem by second fix. Our defaults reflect common Australian trade allowances, and can be adjusted upwards for non-standard geometry or downwards where experience supports a lower figure.
What this tool does not do
It does not replace a professional quote, factor regional pricing, assess structural adequacy, or confirm National Construction Code (NCC) compliance. Those remain the responsibility of a suitably qualified designer, surveyor, or your building surveyor.
On-site considerations for gps coordinate converter
Boundary disputes are expensive. For plot-critical measurements, commission an RICS-accredited land survey rather than relying on planning drawings.
the National Construction Code (NCC) and compliance
Contaminated land, flood risk, and boundary or dividing-fence considerations all need survey input. boundary or dividing-fence Act 1996 notices are a legal requirement on most boundary-affecting works. When in doubt, a pre-application enquiry to the local council can give early clarity, which tends to be less costly than retrospective correction.
Before you order
Hire rather than buy survey kit unless you will use it weekly. A total station plus operator costs $300–500/day from a survey-hire firm. Cross-checking the calculator’s output against a supplier quote helps catch differences in pricing assumptions — ask for exact product specifications (grade, finish, batch number) and confirm delivery timescales against your programme.
Adjusting the defaults
Every input in this calculator is editable. Enter your own dimensions, supplier prices, and wastage allowance — the output recalculates instantly. If the defaults feel off for your region or project type, your own numbers always override them.
Using this gps coordinate converter alongside other BuildMetricLab tools
This calculator works best as part of a planning workflow. Pair the quantity with our project contingency, labour-hours, and material-cost calculators to build a complete estimate before you pick up the phone to a supplier. All BuildMetricLab tools run entirely in your browser — no sign-up, no data sent anywhere, and every formula is shown on-page so you can audit the maths.
Sources & methodology
Converts GPS coordinates between decimal degrees and degrees-minutes-seconds (DMS) format using decimal = degrees + minutes/60 + seconds/3600, with hemisphere (N/S/E/W) setting the sign. Every result is calculated from the values you enter, and all inputs are editable.
Frequently asked questions
Are GPS coordinate converter results accurate enough for legal or cadastral use?
No. This tool only performs the arithmetic conversion between decimal degrees and degrees-minutes-seconds (DMS) for the values you enter. It does not perform datum transformations, account for coordinate reference system differences, or establish legal boundaries. For cadastral surveys or boundary determination, consult a registered surveyor.
What datum does this converter assume?
The tool performs a pure numeric conversion and does not apply or verify any datum (e.g. GDA2020 or WGS84). Coordinates you enter and receive back are assumed to already be in the same reference datum.
Does this tool replace a registered surveyor?
No. This tool only reformats coordinates you enter between decimal degrees and DMS. It does not perform datum transformations or establish legal boundaries. For cadastral surveys or boundary determination, consult a registered surveyor.
Why does the DMS result show different seconds after converting back from decimal degrees?
Small differences can appear due to floating-point rounding in the minutes/seconds split. The displayed result is rounded only at the final output step; the underlying conversion itself is exact arithmetic.
