Convert Gram-force to Petanewton

Gram-force [gf]

Petanewton [PN]

Unit definitions

Gram-force is the force exerted by a mass of one gram in standard gravity ($gₙ$) ($1\ \text{kgf} = 9.806\,65\ \text{N}$).

${10}^{15}$ newtons equal one petanewton.

$$\text{Force}_{\text{PN}} = \text{Force}_{\text{gf}} \cdot 9.80665e - 18$$

Convert $20.0\ \text{gf}$ to $\text{PN}$.

$$\text{Force}_{\text{PN}} = 20.0 \cdot 9.80665e - 18$$

$$\text{Force}_{\text{PN}} = 0.000000000000000196133$$

$$\therefore \ 20.0\ \text{gf} = 0.000000000000000196133 \ \text{PN}$$

Convert $70.0\ \text{gf}$ to $\text{PN}$.

$$\text{Force}_{\text{PN}} = 70.0 \cdot 9.80665e - 18$$

$$\text{Force}_{\text{PN}} = 0.0000000000000006864655$$

$$\therefore \ 70.0\ \text{gf} = 0.0000000000000006864655 \ \text{PN}$$

Convert $105.0\ \text{gf}$ to $\text{PN}$.

$$\text{Force}_{\text{PN}} = 105.0 \cdot 9.80665e - 18$$

$$\text{Force}_{\text{PN}} = 0.00000000000000102969825$$

$$\therefore \ 105.0\ \text{gf} = 0.00000000000000102969825 \ \text{PN}$$

Convert $145.0\ \text{gf}$ to $\text{PN}$.

$$\text{Force}_{\text{PN}} = 145.0 \cdot 9.80665e - 18$$

$$\text{Force}_{\text{PN}} = 0.00000000000000142196425$$

$$\therefore \ 145.0\ \text{gf} = 0.00000000000000142196425 \ \text{PN}$$

Convert $170.0\ \text{gf}$ to $\text{PN}$.

$$\text{Force}_{\text{PN}} = 170.0 \cdot 9.80665e - 18$$

$$\text{Force}_{\text{PN}} = 0.0000000000000016671305$$

$$\therefore \ 170.0\ \text{gf} = 0.0000000000000016671305 \ \text{PN}$$
