Heat Ratings. The output of a radiator is measured in British Thermal Units (BTU.s) per hour. (So is air-conditioning, come to that!) 3000 BTU is roughly equivalent to a 1 kilowatt bar heater, just to give you some idea.

If you live in a place where it gets cold often, or during the winter time, you will get better results using 5w30.Otherwise 10w30 oil is good enough, i usually use 5w30 all year round.ating Newest Oldest.

As it says Actual at the temperature and pressure conditions stated. To convert Nm3/hr to Sm3/hr it's a ratio of the absolute temperatures -. (The difference between 0 and 15.5 deg C). 10 Nm3/hr *(15.6+273)/ (0+273) = 10.57 Sm3/hr.Where -273 is absolute zero on the temperature scale. To convert either of the above to Am3/hr or m3/hr (as normally written). you need to convert both the temperature and pressure ratios. 10 Nm3/hr .....s it says Actual at the temperature and pressure conditions stated. To convert Nm3/hr to Sm3/hr it's a ratio of the absolute temperatures -. (The difference between 0 and 15.5 deg C). 10 Nm3/hr *(15.6+273)/ (0+273) = 10.57 Sm3/hr.
