R & RSI Value Converter
Understanding Thermal Resistance Values
Both R and RSI values indicate how effectively insulation resists heat transfer. RSI is based on the metric system, while R-value is its imperial equivalent. Use the reference chart below to quickly compare insulation performance values.
| R-Value (Imperial) | RSI Value (Metric) |
|---|---|
| R-5 | RSI 0.88 |
| R-10 | RSI 1.76 |
| R-15 | RSI 2.64 |
| R-20 | RSI 3.52 |
| R-25 | RSI 4.40 |
| R-30 | RSI 5.28 |
Conversion Formula: RSI = R × 0.1761 | R = RSI × 5.678
