Dew Point Temperature Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.
公式
Td ≈ T - ((100 - RH) / 5) (Magnus approximation)
分步指南
- 1Enter current temperature and relative humidity
- 2Apply the formula using your project measurements
- 3Add required safety factors or waste allowances per code
例题解析
输入
75°F air temperature, 60% RH
结果
Dew Point ≈ 75 - (40/5) = 75 - 8 = 67°F
常见错误注意事项
- ✕Not applying code-required safety factors or derating
- ✕Forgetting to account for waste and cut losses in material estimates
