1. BTU per hour to watts

The British thermal unit per hour (symbol: Btu/h) is a United States customary system unit of power. This unit is often abbreviated as simply "Btu," which is the same abbreviation used for British thermal units, a measurement of heat. One watt, the International System of Units derived unit of power, is equal to approximately 3.41214 Btu/h.

A watt (Symbol: W) is the SI (International System of Units) derived unit of power. It is defined as 1 joule per second and is used to quantify the rate of energy transfer.

How to convert BTU/hr to watts

1 BTU/hr = 0.29307107 W

So the power P in watts (W) is equal to the power P in BTUs per hour (BTU/hr) times 0.29307107 and is equal to the power P in BTUs per hour (BTU/hr) divided by 3.412141633:

P_(W) = P_(BTU/hr) × 0.29307107 = P_(BTU/hr) / 3.412141633

Example

Convert 20000 BTU/hr to watts:

P_(W) = 20000 BTU/hr / 3.412141633 = 5861.42W

2. Btu Per Hour to Kilowatts

Btu per hour and kilowatts are both units used to measure power.

One BTU per hour is equal to one british thermal unit, or the energy needed to heat one pound of water 1 °F, for one hour.

The btu per hour is a US customary unit of power. Btu per hour can be abbreviated as Btu/h; for example, 1 btu per hour can be written as 1 Btu/h. In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.

One kilowatt is the power equal to 1,000 watts, or the energy consumption at a rate of 1,000 joules per second.

The kilowatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "kilo" is the prefix for 10₃. Kilowatts can be abbreviated as kW; for example, 1 kilowatt can be written as 1 kW.

How to convert BTU/hr to kW

1 BTU/hr = 0.00029307107 kW

So the power conversion of BTU_IT/hr to kW is given by the formula:

P_(kW) = P_(BTU/hr) / 3412.142

4. Fraction to Decimal

In fractions, the numerator is the number above the line and the denominator is the number below.

The line in a fraction that separates the numerator and the denominator represents division.

To convert a fraction to a decimal, divide the numerator by the denominator.

How to convert fractions to decimals

A fraction is made up of two parts: a numerator and a denominator. It is used to represent how many parts we have out of the total number of parts.

The line in a fraction that separates the numerator and denominator can be rewritten using the division symbol.

So, to convert a fraction to a decimal, divide the numerator by the denominator. If required, you can use a calculator to do this. This will give us our answer as a decimal.

Examples

⁴/₅ as a decimal is 4 ÷ 5 = 0.8

⁷⁵/₁₀₀ as a decimal is 75 ÷100 = 0.75

³/₆ as a decimal is 3 ÷ 6 = 0.5

5. Watts to kilowatts

A watt (Symbol: W) is the SI (International System of Units) derived unit of power. It is defined as 1 joule per second and is used to quantify the rate of energy transfer.

A kilowatt (symbol: kw) is a unit of power in the International System of Units (SI). The base unit of the kilowatt is the watt, which was named after Scottish inventor James Watt. As is consistent with SI units, the prefix kilo- means that a kilowatt equals one thousand watts or one thousand joules per second.
