Pole Metric / Imperial Converter

Height / length in feet + in. ↔ metres, plus pole circumference, diameter, embedment, force, stress and wind pressure conversions.

Height / Length: ft + in. → m

0.000 m

Uses 1 ft = 0.3048 m and 1 in = 25.4 mm.

Height / Length: m → ft + in.

0.00 ft / 0 ft 0.0 in

General purpose height or length conversion. Shows decimal feet first, then feet + inches.

Circumference: in. ↔ mm

0.0 in / 0 mm

Diameter from Circumference

0.0 in / 0 mm diameter

Diameter = circumference / pi. Handy when comparing US pole class data with metric pole measurements.

Quick Height / Length Presets

Pole Height / Length + Embedment

1/6th of pole length rule Embedment 0.000 m / 0.00 ft, pole length 0.000 m / 0.00 ft
US rule: 10% of pole height + 2 ft Embedment 0.000 m / 0.00 ft, pole length 0.000 m / 0.00 ft

Use this when the general height / length conversion also needs embedment, the portion of the pole underground.

Force Conversion

0.0 kN / 0 lbf

Useful for ANSI pole class ratings, tip load and failure load comparisons.

Stress Conversion

0.0 MPa / 0.0 kpsi

1 ksi = 6.89476 MPa. Common for timber fibre stress and modulus values.

Wind Pressure

0 Pa / 0.0 km/hr

Uses the AS/NZS 7000:2016 relationship q = 0.6 x (V/3.6)^2, where V is wind speed in km/hr.
