## British thermal unit

British thermal unit, abbr. Btu, unit for measuring heat quantity in the customary system of English units of measurement, equal to the amount of heat required to raise the temperature of one pound of water at its maximum density [which occurs at a temperature of 39.1 degrees Fahrenheit (℉) ] by 1℉. The Btu may also be defined for the temperature difference between 59℉ and 60℉. One Btu is approximately equivalent to the following: 251.9 calories; 778.26 foot-pounds; 1055 joules; 107.5 kilogram-meters; 0.0002928 kilowatt-hours. A pound (0.454 kilogram) of good coal when burned should yield 14,000 to 15,000 Btu; a pound of gasoline or other fuel oil, approximately 19,000 Btu.

As the starting date for thermal unit accumulation increased from DOY 100 to 200, the time required to accumulate 200[degrees]C d progressively decreased from 22 to 10 d, which reflects the increasing temperatures for the later starting dates Using the cardinal temperature values of Baker and Reddy (2001), the number of days required to cumulate 200[degrees]C d beginning on DOY 100 was 22 d using HTU and 24 d using DTU, which differed significantly during the 43 yr period (Table 1).
