# Convert circular thou to rai

Learn how to convert 1 circular thou to rai step by step.

## Calculation Breakdown

Set up the equation
$$1.0\left(circular \text{ } thou\right)={\color{rgb(20,165,174)} x}\left(rai\right)$$
Define the base values of the selected units in relation to the SI unit $$\left(square \text{ } meter\right)$$
$$\text{Left side: 1.0 } \left(circular \text{ } thou\right) = {\color{rgb(89,182,91)} 5.06707479097498 \times 10^{-10}\left(square \text{ } meter\right)} = {\color{rgb(89,182,91)} 5.06707479097498 \times 10^{-10}\left(m^{2}\right)}$$
$$\text{Right side: 1.0 } \left(rai\right) = {\color{rgb(125,164,120)} 1.6 \times 10^{3}\left(square \text{ } meter\right)} = {\color{rgb(125,164,120)} 1.6 \times 10^{3}\left(m^{2}\right)}$$
Insert known values into the conversion equation to determine $${\color{rgb(20,165,174)} x}$$
$$1.0\left(circular \text{ } thou\right)={\color{rgb(20,165,174)} x}\left(rai\right)$$
$$\text{Insert known values } =>$$
$$1.0 \times {\color{rgb(89,182,91)} 5.06707479097498 \times 10^{-10}} \times {\color{rgb(89,182,91)} \left(square \text{ } meter\right)} = {\color{rgb(20,165,174)} x} \times {\color{rgb(125,164,120)} {\color{rgb(125,164,120)} 1.6 \times 10^{3}}} \times {\color{rgb(125,164,120)} \left(square \text{ } meter\right)}$$
$$\text{Or}$$
$$1.0 \cdot {\color{rgb(89,182,91)} 5.06707479097498 \times 10^{-10}} \cdot {\color{rgb(89,182,91)} \left(m^{2}\right)} = {\color{rgb(20,165,174)} x} \cdot {\color{rgb(125,164,120)} 1.6 \times 10^{3}} \cdot {\color{rgb(125,164,120)} \left(m^{2}\right)}$$
$$\text{Cancel SI units}$$
$$1.0 \times {\color{rgb(89,182,91)} 5.06707479097498 \times 10^{-10}} \cdot {\color{rgb(89,182,91)} \cancel{\left(m^{2}\right)}} = {\color{rgb(20,165,174)} x} \times {\color{rgb(125,164,120)} 1.6 \times 10^{3}} \times {\color{rgb(125,164,120)} \cancel{\left(m^{2}\right)}}$$
$$\text{Conversion Equation}$$
$$5.06707479097498 \times 10^{-10} = {\color{rgb(20,165,174)} x} \times 1.6 \times 10^{3}$$
Switch sides
$${\color{rgb(20,165,174)} x} \times 1.6 \times 10^{3} = 5.06707479097498 \times 10^{-10}$$
Isolate $${\color{rgb(20,165,174)} x}$$
Multiply both sides by $$\left(\dfrac{1.0}{1.6 \times 10^{3}}\right)$$
$${\color{rgb(20,165,174)} x} \times 1.6 \times 10^{3} \times \dfrac{1.0}{1.6 \times 10^{3}} = 5.06707479097498 \times 10^{-10} \times \dfrac{1.0}{1.6 \times 10^{3}}$$
$$\text{Cancel}$$
$${\color{rgb(20,165,174)} x} \times {\color{rgb(255,204,153)} \cancel{1.6}} \times {\color{rgb(99,194,222)} \cancel{10^{3}}} \times \dfrac{1.0}{{\color{rgb(255,204,153)} \cancel{1.6}} \times {\color{rgb(99,194,222)} \cancel{10^{3}}}} = 5.06707479097498 \times 10^{-10} \times \dfrac{1.0}{1.6 \times 10^{3}}$$
$$\text{Simplify}$$
$${\color{rgb(20,165,174)} x} = \dfrac{5.06707479097498 \times 10^{-10}}{1.6 \times 10^{3}}$$
Rewrite equation
$$\dfrac{1.0}{10^{3}}\text{ can be rewritten to }10^{-3}$$
$$\text{Rewrite}$$
$${\color{rgb(20,165,174)} x} = \dfrac{10^{-3} \times 5.06707479097498 \times 10^{-10}}{1.6}$$
$$\text{Simplify}$$
$${\color{rgb(20,165,174)} x} = \dfrac{10^{-13} \times 5.06707479097498}{1.6}$$
Solve $${\color{rgb(20,165,174)} x}$$
$${\color{rgb(20,165,174)} x}\approx3.1669217444 \times 10^{-13}\approx3.1669 \times 10^{-13}$$
$$\text{Conversion Equation}$$
$$1.0\left(circular \text{ } thou\right)\approx{\color{rgb(20,165,174)} 3.1669 \times 10^{-13}}\left(rai\right)$$
