  Coal vs Fuel Oil  
     
  BTUs  
Coal:  13,500
(good steaming coal used by the US Navy) - "Principles of Oil and Gas Production", 1916
Oil:  18,900
US Bureau of Mines cited in "Principles of Oil and Gas Production", 1916
  Fuel Stored in 43 Cubic Feet  
 Coal:  One Ton
("General Information U.S.S. 'TEXAS' finished plans Nos. 37 and 38" , pg 26, Coal Bunker Capacities)
  Fuel Oil:  7.26 barrels
((43 * 7.48) / 42)  * 0.95 
*** 43 cubic feet
*** 7.48 gallons of liquid per cubic foot
*** 42 gallons per barrel
*** 0.95 allowance for expansion
 
  Relative Heating Effect of Coal vs Fuel Oil  
  (43 cubic feet)  
   "Marine Steam", Babcock and Wilcox, 1914  
     
1 ton coal = 4.60 barrels of fuel oil
7.26 barrels fuel oil = 1.58 tons of coal

  1935 Fuel Use Data  
USN Fuel Allowance Table - July 1935
 Columns right of GPH: my calculations from Knots, RPM and GPH, plus distance at 10knots of speed
NM: nautical mile
PLACE: among the 15 battleships, by gals consumed per hour
Miles: Two sources list 15,000 knots and 15,400 knots at 10knots per hour.
At 15,200 knots fuel use comes to 1,156,720 gallons. 
BB35 newspaper of 27 September 1927 reports 1,500,000 gallons as maximum capacity. 
The 1,156,720 figure was used to calculate miles at the other speeds
