CONVERSION

S/1000

℃> 17

S=1305(hydrometer -1)+( ℃-17.5)×0.3

Result

℃< 17

S=1305(hydrometer -1)+( 17.5-℃)×0.2

Result

Hydrometers are calibrated by temperature。

※ºC=5/9*(ºF-32) Fahrenheit

 

Rough conversion

  1. A= Take thousandths and ten thousandths as number in hydrometer(EX 1.025 as 25)
  2. B=A×0.3=25×0.3=7.5
  3. Salinity=A+B=25+7.5=22.1 (1/1000)
