Convert BTU to calorie

Learn how to convert 1 BTU to calorie step by step.

Calculation Breakdown

Set up the equation

1.0 (B T U) = x (c a l o r i e)

Define the base values of the selected units in relation to the SI unit

(j o u l e)

Left side: 1.0 (B T U) = 1054.5 (j o u l e) = 1054.5 (J)

Right side: 1.0 (c a l o r i e) = 4.1868 (j o u l e) = 4.1868 (J)

Insert known values into the conversion equation to determine

x

1.0 (B T U) = x (c a l o r i e)

Insert known values =>

1.0 \times 1054.5 \times (j o u l e) = x \times 4.1868 \times (j o u l e)

Or

1.0 \cdot 1054.5 \cdot (J) = x \cdot 4.1868 \cdot (J)

Cancel SI units

1.0 \times 1054.5 \cdot (J) = x \times 4.1868 \times (J)

Conversion Equation

1054.5 = x \times 4.1868

Switch sides

x \times 4.1868 = 1054.5

Isolate

x

Multiply both sides by

(\frac{1.0}{4.1868})

x \times 4.1868 \times \frac{1.0}{4.1868} = 1054.5 \times \frac{1.0}{4.1868}

Cancel

x \times 4.1868 \times \frac{1.0}{4.1868} = 1054.5 \times \frac{1.0}{4.1868}

Simplify

x = \frac{1054.5}{4.1868}

Solve

x

x \approx 251.86299799 \approx 2.5186 \times 10^{2}

Conversion Equation

1.0 (B T U) \approx 2.5186 \times 10^{2} (c a l o r i e)
