Fieldwork: Engineering Toolkit

Fieldwork brings everyday technical calculations, unit conversion and illustrated component references into one offline Android workspace.

69 CALCULATORS

Electrical: single and three-phase power, appliance load schedules, energy costs, voltage drop, power factor, resistance, batteries, motors and solar PV estimates.

HVAC: room cooling estimates, chilled-water duty and flow, refrigerant enthalpy calculations, chiller COP, heat rejection, air flow, ventilation, humidity and dew point.

Civil and quantity surveying: concrete, footings, columns, rebar, excavation, backfill, masonry, formwork, plaster, paint, tiles and quantity cost build-ups.

Water and piping: flow, velocity, pipe bore, pressure loss and pump power.

Mechanics, physics and mathematics: torque, shaft power, motion, projectile trajectories, energy, waves, lighting, geometry, percentages and interpolation.

21 UNIT CONVERSION GROUPS

Convert lengths, areas, masses, volumes, temperature, flow, pressure, power, energy, torque and electrical units in both directions. Convert BTU/h to refrigeration tons and back, with clear distinctions between energy and power.

FITTINGS AND PROJECT RECORDS

Explore original illustrated references for elbows, tees, reducers, flanges, valves, fasteners and electrical connections. Capture asset specifications, review declared connection mismatches and identify missing evidence. Save calculation inputs, results and assumptions to named projects, and copy reports or JSON exports.

BUILT FOR YOUR FIELD

Industry profiles highlight tools for MEP, construction, oil and gas, and facilities management. Six regional presets provide editable voltage and currency starting values. All calculators remain available.

VISIBLE METHODS

Field explanations, formulas, units and limitations accompany each calculation. Results are calculation guidance, not certified design or a manufacturer specification database. Verify project rules, standard editions and actual equipment information before installation.

OFFLINE AND PRIVATE

No account, advertising, analytics or cloud synchronisation. Records are stored on your device; Android backup settings may apply. English interface, SI calculator inputs and metric/imperial conversion. Android 7.0 or later.
