Convert Gram-force to Femtonewton

Gram-force [gf]

Femtonewton [fN]

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 femtonewton.

$$\text{Force}_{\text{fN}} = \text{Force}_{\text{gf}} \cdot 9806650000000$$

Convert $40.0\ \text{gf}$ to $\text{fN}$.

$$\text{Force}_{\text{fN}} = 40.0 \cdot 9806650000000$$

$$\text{Force}_{\text{fN}} = 392266000000000$$

$$\therefore \ 40.0\ \text{gf} = 392266000000000 \ \text{fN}$$

Convert $60.0\ \text{gf}$ to $\text{fN}$.

$$\text{Force}_{\text{fN}} = 60.0 \cdot 9806650000000$$

$$\text{Force}_{\text{fN}} = 588399000000000$$

$$\therefore \ 60.0\ \text{gf} = 588399000000000 \ \text{fN}$$

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

$$\text{Force}_{\text{fN}} = 105.0 \cdot 9806650000000$$

$$\text{Force}_{\text{fN}} = 1029698250000000$$

$$\therefore \ 105.0\ \text{gf} = 1029698250000000 \ \text{fN}$$

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

$$\text{Force}_{\text{fN}} = 145.0 \cdot 9806650000000$$

$$\text{Force}_{\text{fN}} = 1421964250000000$$

$$\therefore \ 145.0\ \text{gf} = 1421964250000000 \ \text{fN}$$

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

$$\text{Force}_{\text{fN}} = 170.0 \cdot 9806650000000$$

$$\text{Force}_{\text{fN}} = 1667130500000000$$

$$\therefore \ 170.0\ \text{gf} = 1667130500000000 \ \text{fN}$$
