+# Conversion factors for tunits task
+#
+# Read this table as "There are <factor> <from> in a <to>."
+# For example, "There are 100 centimeters in a meter." 
+# The last column, swap, does not change the sense of the sentence
+# but does change the direction that the conversion is applied,
+# For example, "60 seconds in a minute" is actually a conversion 
+# from minutes to seconds because swap is yes. Unit conversions
+# should set swap to yes when the desired conversion is not an exact
+# value, but its inverse is. Only one conversion is allowed per
+# unit, which simplifies the program logic considerably. Conversions
+# should be chosen so that they ultimately resolve to MKS units. To
+# prevent endless loops conversions from the fundamental units are
+# checked for and forbidden. However, the program does not check for
+# other loops, so be careful when adding new conversions!
