That's only about 7 tons of hard pressed snow.
make that 20..40 tons (~300..600kg/m3)
...you would need 70,000kcal/degree to melt...
If you can't wait until July, 35,000 Cal per degree (C|K)
should do - kcal / Cal / Kal = kilo-calorie
1 Cal = 1kg water / degree (C|K)
Hopefully I made my point in favor of SI !
Domesting heating is measured in BTU;
British Thermal Units.
cooling in tons (of
melting ice?) and fuel energy is billed in therms (whatever
that is)
Probably British Thermal Units.
Hubble's constant has unit km/sec/Mpc (which reduces to Hz
with some minuscule coefficient.)
