**Significant**Figure Rules 1. Non-zero **digits** are always **significant**. 2. Any zeros between two **significant digits** are **significant**.

## How many significant figures does 200 have?

Trailing zeros

**are**only**significant**if the number contains a decimal point. For example, the number**200 has**only one**significant**figure, while the number**200**.**has**three, and the number 200.00**has**five**significant figures**.## How many significant figures does 30.00 have?

Explanation : In a number with decimal, zeros on the right of the last non-zero

**digit are significant**. Therefore**30.00 has**four**significant figures**.## How many significant figures does 50 have?

Example: 50.00 (4

**significant figures**),**50**(1**significant**figure),**50**. (2**significant figures**).## How many significant figures does 0.020 have?

**0.020 has**two

**significant figures**. The 2 is

**significant**because all non-zero numbers

**are**signficant. The second 0 is

**significant**because all zeros at the end of a decimal

**are significant**.

## How many significant figures does 0.0560 have?

the

**significant figures**of the number**0.0560**is 3.## How many significant figures does 0.100 have?

There are three

**significant figures**in**0.100**cm, 0.110 cm, and 1.00 cm. Zeros preceding the first nonzero**digit**are not**significant**. There are three**significant figures**in 0.0101 cm, 0.00100 cm and 0.000101 cm. Terminal zeros in a number without an explicit decimal point may or may not be**significant**.## How many significant digits do 10.097 have?

The number

**10.097 has**5**significant**figures.## How many significant figures does 1500.00 have?

Thus, in

**1,500**m, the two trailing zeros are not**significant**because the number is written without a decimal point; the number**has**two**significant figures**. However, in**1,500.00**m, all six**digits**are**significant**because the number**has**a decimal point.## How many significant figures does 0.006 have?

Case | Examples | |
---|---|---|

Zeros on the right of the first non-zero digit | 0.03800 | 4 |

are significant | 3,6000,000 | 7 |

Zeros on the left of the first non-zero digit | 0.006 | 1 |

are not significant | 0.0352 | 3 |

## How many significant figures does 0.001 have?

Example:

**0.001**, 1 is the**significant**figure, hence**0.001 has**one**significant**figure. Trailing zeros before the decimal point**do**not count. Example: 10, 100, 1000 all**have**only one**significant**figure.## How many significant figures does 0.350 have?
