How to report

Report an error by email — ianwelkins@gmail.com

What to include

• The page — paste its address, or its name (for example, the kVA to Amps Chart).
• The values you entered: kVA or amps, the voltage, and single-phase or three-phase.
• The result the site gave you, and the result you expected, with your source if you have one.
• For a chart value: the row (kVA) and the column (voltage) where you saw it.

Before you send — three quick checks

Most surprising results turn out to be one of these, and checking them first may save you an email:

• Phase mode: was the calculator set to single-phase or three-phase? The same kVA differs by a factor of √3 between them.
• Voltage type: three-phase, was your voltage line-to-line (400V) or line-to-neutral (230V)? The three-phase page has a mode for each.
• Power factor: if your expected figure came from a kW calculation, it will differ — kVA to amps never uses a power factor. The methodology page proves why.

What happens next

Your report is reproduced with your values, checked against the standards on the methodology page, and answered by email. If the site is wrong, the fix ships in the next update and the correction is noted on the affected page. The process is described in full in the editorial policy.

Thank you for taking the time — a reported error helps everyone who uses the tool after you.
