Convert US Survey foot to Astronomical unit

US Survey foot [sFT]

Astronomical unit [ua]

Unit definitions

A US survey foot is a unit of length equal to $\frac{1\,200}{3\,937}$ meters.

An astronomical unit is the average distance from the center of the Earth to the center of the Sun.

$$\text{Length}_{\text{ua}} = \text{Length}_{\text{sFT}} \cdot 2.037466229799881786943140473521149e - 12$$

Convert $50.0\ \text{sFT}$ to $\text{ua}$.

$$\text{Length}_{\text{ua}} = 50.0 \cdot 2.037466229799881786943140473521149e - 12$$

$$\text{Length}_{\text{ua}} = 0.0000000001018733114899940893471570236760574$$

$$\therefore \ 50.0\ \text{sFT} = 0.0000000001018733114899940893471570236760574 \ \text{ua}$$

Convert $85.0\ \text{sFT}$ to $\text{ua}$.

$$\text{Length}_{\text{ua}} = 85.0 \cdot 2.037466229799881786943140473521149e - 12$$

$$\text{Length}_{\text{ua}} = 0.0000000001731846295329899518901669402492977$$

$$\therefore \ 85.0\ \text{sFT} = 0.0000000001731846295329899518901669402492977 \ \text{ua}$$

Convert $120.0\ \text{sFT}$ to $\text{ua}$.

$$\text{Length}_{\text{ua}} = 120.0 \cdot 2.037466229799881786943140473521149e - 12$$

$$\text{Length}_{\text{ua}} = 0.0000000002444959475759858144331768568225379$$

$$\therefore \ 120.0\ \text{sFT} = 0.0000000002444959475759858144331768568225379 \ \text{ua}$$

Convert $140.0\ \text{sFT}$ to $\text{ua}$.

$$\text{Length}_{\text{ua}} = 140.0 \cdot 2.037466229799881786943140473521149e - 12$$

$$\text{Length}_{\text{ua}} = 0.0000000002852452721719834501720396662929609$$

$$\therefore \ 140.0\ \text{sFT} = 0.0000000002852452721719834501720396662929609 \ \text{ua}$$

Convert $180.0\ \text{sFT}$ to $\text{ua}$.

$$\text{Length}_{\text{ua}} = 180.0 \cdot 2.037466229799881786943140473521149e - 12$$

$$\text{Length}_{\text{ua}} = 0.0000000003667439213639787216497652852338068$$

$$\therefore \ 180.0\ \text{sFT} = 0.0000000003667439213639787216497652852338068 \ \text{ua}$$
