Use this construction calculation for preliminary quantity, geometry, material, load, or coverage planning when dimensions and units have been measured consistently.

Horizontal Run Meters (m)

Required number input.

Vertical Rise Meters (m)

Required number input.

Horizontal run per unit vertical rise of an excavation slope; this geometric ratio is not a safe-slope determination. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Horizontal To Vertical Ratio

The resulting horizontal to vertical ratio returned as a number.

• Earthwork volumes depend on survey surfaces, soil variability, swell and shrink factors, compaction target, groundwater, side slopes, haul conditions, and temporary works. Geotechnical and site-safety requirements remain separate.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Verify dimensions on site, use current product data and local code requirements, include an explicit waste or safety allowance where appropriate, and obtain qualified structural, electrical, plumbing, or geotechnical review when required.

• Roof Pitch Angle

  Calculate a roof slope angle from vertical rise and horizontal run, not the rafter length.

• Hunter Fixture Units

  Sum fixture-unit loads from parallel fixture counts and assigned units per fixture; this is not the Hunter demand-curve conversion to flow.

• Drain Slope Fall Per Foot

  Convert a drain's horizontal run in feet and specified fall in inches per foot into total fall.
