To convert watts to BTU/h, we need to now how the two units of power relate. Therefore, lets begin by defining each of them. Watt is the SI unit of power, equivalent to one joule per second while BTU is defined as the quantity of heat required to raise the temperature of 454 grams of water from 60 to 61 degrees Fahrenheit.

BTU/h is a unit of measurement for energy or heat and it stands for British Thermal Unit per hour.

### Formula to Convert W to BTU/h.

To convert them, we need to know how they are related.

We are told that 1 W is equal to 3.412141633 BTU/h.

Therefore, to convert w to BTU/h, we multiply the W value by 3.412141633.

**Example 1:**

Convert 200 Watts to BTU/h.

**= 200 x 3.412141633**

**= 682 BTU/h.**

**Example 2:**

Convert 0.03 W to BTU/h.

**1 W = 3.41 2141633 BTU/h**

**= 0.03 x 3.412141633**

**= 0.10236424899 BTU/h**

**Example 3.**

Convert 1000,000W to BTU/h.

**1 W = 3.4 12141633 BTU/h**

**= 1,000,000 x 3.4 12141633**

**= 3,412,141.6333 BTU/h.**
