Re-entering values
A change in power or current can force you to type the same project information into another calculator.
CONNECTED ELECTRICAL CALCULATIONS FOR ENGINEERS AND ELECTRICIANS
When the circuit changes, your calculations should change with it.
Stop rebuilding the same electrical context in separate tools.
The next time a load, voltage, or power-factor assumption changes, you should not have to recreate the same setup across several calculators. WattsWise keeps related power, current, voltage-drop, fault-current, conductor, and diagnostic tools in one Android workspace to reduce repeated setup, while the data behind each calculation remains available for review and manual override.
Install WattsWise on Google PlayA practical first check: use a circuit you already know, enter your own data, and compare the outputs with your usual calculation.
The formula is rarely the frustrating part. Repeating the setup is.
Picture the next design revision: the load changes, current deserves another look, and voltage drop may need to be checked again. The arithmetic may be familiar, but the same project context often has to move from one isolated tool to another.
Re-checking assumptions
A copied value may still be correct mathematically but belong to an earlier design condition.
Rebuilding context
Separate calculators can each produce a valid result while you remain responsible for keeping the assumptions aligned between them.
WattsWise was built around a simpler idea: reuse relevant context where calculations are connected, and keep manual control when the engineering case requires a different input.
Connected where it helps. Manual where it matters.
Use the values you actually have
Enter the electrical data available for the circuit, load, or check you are performing.
Carry relevant context forward
Where modules are connected, WattsWise can reuse relevant electrical values instead of asking you to re-enter the same information.
Review relationships, not only isolated answers
Power, current, power factor, and voltage drop are related. When you revisit a project, the connected workflow makes those relationships easier to follow.
For example, if active power changes, you can review the resulting current and then revisit voltage drop using the updated context. If that check needs a different current, enter it manually.
Override an input when the assumption changes
Connected does not mean locked. If one calculation needs a different value, change it deliberately and proceed with that case. In other words, connection is useful because it preserves context without removing your control.
Keep more attention on the engineering, less on carrying numbers between tools.
In a separated workflow
- open another calculator;
- enter project values again;
- remember which assumptions changed;
- compare results across different screens or files;
- repeat the handoff when another input changes.
In WattsWise
- Keep related calculations in one toolset.
- Reuse relevant values where modules are connected.
- Change inputs deliberately when assumptions differ.
- Return to a related calculation without recreating the whole context.
- Review the result as an engineering input, not as automatic design approval.
The benefit is not a promised number of minutes saved. It is a more coherent calculation workflow with fewer unnecessary handoffs between isolated tools.
Keep the electrical calculations you return to close together.
Power Triangle
Work with active, reactive, and apparent power, power factor, current, and voltage while keeping the relationships among those quantities visible.
Useful when: the information you receive may begin with a different known variable and you want to work from what is actually available.
Voltage Drop
Calculate voltage drop in volts and percent for supported single-phase and three-phase configurations using the K method (resistivity), with current derived from the connected workflow or entered manually when appropriate. The current listing also describes AC and DC support.
Useful when: a load or current assumption changes and you want to review the resulting drop without recreating the whole setup.
Short-Circuit / Fault-Current Estimates
Run point-to-point fault-current estimates using module inputs such as source voltage and transformer impedance (%Z), then use the result as a calculation aid for further engineering review.
Useful when: you need an estimate to support a check, not an automatic approval of a protection design.
Conductor & Conduit Utilities
Use recurring utilities such as AWG ↔ mm² conversion and conduit-fill calculations inside the same toolset.
Useful when: small recurring tasks around a calculation should not require another app or reference page.
PRO
More analysis when the project goes beyond the core calculations.
According to the current WattsWise product listing, these advanced capabilities are presented as Pro features where applicable.
Power-Factor Correction
Calculate capacitor-bank requirements in kVAR using the project inputs provided to the module.
Current Imbalance
Review phase-current asymmetry, with advanced analysis using symmetrical components and negative sequence where applicable.
Insulation Resistance, DAR & PI
Record insulation-test readings and calculate diagnostic ratios such as DAR and PI, including temperature-related calculation support where available.
Project Files
Export project configurations as JSON and restore them later so recurring work can resume from saved data instead of an empty workspace.
To be clear: Pro capabilities should be presented as Pro. They should not be implied to be part of the free/core feature set when they are not.
A useful calculator should make the arithmetic easier—not make the engineering invisible.
WattsWise supports electrical calculation work while keeping the user responsible for the assumptions behind it.
- Visible inputs: review the values used by the calculation.
- Manual control: override connected values when your scenario requires a different assumption.
- Configurable context: work with supported voltage settings and 50 Hz / 60 Hz frequency contexts for different systems and regions; the scope is limited to options supported by the released app.
- Engineering judgment remains yours: applicable NEC, IEC, local-code, project, equipment, and safety requirements still need to be checked for the real installation.
WattsWise helps with calculations. It does not certify code compliance, protection coordination, equipment suitability, or final design acceptance.
Try WattsWise against a circuit you already know.
You do not need a marketing video to decide whether the connected workflow is useful for you. Use your own data and a circuit whose result you can verify independently.
- Enter the values you already trust.
- Review the result against your usual method.
- Change one relevant input.
- Check how the related calculation responds.
- Override a shared value if your case needs a different assumption.
The next time a project value changes, you will be able to judge the benefit on your own terms: did the workflow reduce repeated setup while keeping the engineering visible?
For you, that is the useful test. What matters to you is not a claim about speed; it is whether the tool fits your way of checking the work. Your criterion remains the final one.
Built for people who want to understand the numbers they use.
Electrical engineers
For recurring calculations, early-stage checks, field review, and technical exploration when related values need to stay close at hand.
Electricians and contractors
For practical circuit calculations and utilities that can travel with the job instead of living in several separate tools.
Technical students
For exploring relationships among power, current, power factor, voltage drop, and other electrical quantities while still seeing the inputs behind the result.
Not a substitute for engineering responsibility
If the decision requires formal compliance, equipment selection, protection coordination, or design approval, use WattsWise as a calculation aid—not as the final authority.
Built around a recurring engineering problem: repeated setup.
WattsWise grew out of a simple workflow problem: when a project changes, the same values and assumptions often have to be re-entered across separate calculations.
The goal is not to replace spreadsheets or engineering review. It is to make related electrical calculations easier to revisit, reuse, and adjust while keeping the inputs visible.
That means connected context where it helps and manual control when the engineering case needs a different assumption.
