Math & Numbers
Convert between the three common refrigeration efficiency metrics: COP (dimensionless, W/W), EER (Btu/(W·h)), and SEER (seasonal Btu/(W·h)). Standard relations: COP = EER / 3.412, EER = COP × 3.412, SEER = EER / α (α seasonal weighting factor, default 0.875, adjustable 0.8–0.91 to match regional standards such as ARI 210/240). Enter any one metric and all three are reported.
Call this tool from your code in three languages.

POST https://api.elysiatools.com/en/api/tools/eer-seer-converter| Name | Type | Required | Description |
|---|---|---|---|
| fromMetric | select | No | Which metric the Input Value represents. The other two are computed from it. |
| value | number | Yes | Value of the selected Input Metric. |
| seerEerFactor | number | No | Seasonal weighting factor α relating SEER and EER (SEER = EER/α). Default 0.875 (common US approximation). Adjust to match regional standards (0.8–0.91). |
| decimalPlaces | number | No | — |
