Tacheometry Distance Calculator
Distance and elevation from stadia readings and vertical angle.
Before EDM, the stadia hairs WERE the distance meter: intercept × 100. Still the fastest check that your total station isn't lying — and an exam fixture forever.
Formula
Tacheometry Distance Calculator is a free tacheometry for surveyors, civil engineers and property buyers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Tacheometry Distance Calculator
Distance and elevation from stadia readings and vertical angle. The calculation implements D = k·s·cos²θ; V = k·s·sin2θ/2 (k = 100) (Tacheometric surveying — Punmia). Before EDM, the stadia hairs WERE the distance meter: intercept × 100. Still the fastest check that your total station isn't lying — and an exam fixture forever.

Frequently asked questions
What formula does the Tacheometry Distance Calculator use?+
It computes D = k·s·cos²θ; V = k·s·sin2θ/2 (k = 100), per Tacheometric surveying — Punmia. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
Before EDM, the stadia hairs WERE the distance meter: intercept × 100. Still the fastest check that your total station isn't lying — and an exam fixture forever.
Are regional land units exact?+
Conversion factors follow state revenue-department values noted on the tool. Units like bigha and katha vary by region, so always confirm the local factor named in your land records.
Is the Tacheometry Distance Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
