The Republic of India adopted the metric system on April 1, 1957. So basic measurement units for weight is gram/kilogram, length is meter/kilometer, liquid volume is milliliter/liter. It is the correct and accepted way for Hindi as well. However, other units are still prevalent but particularly for technical translation, we need to follow the metric system. Except for measuring body temperature, generally temperature in India is measured in Celsius. So for Hindi translation, it should be changed in Celsius if in source language, it is in different units.
