[Section titled “How does Hissab AI work? And how does it ensure accurate results?”](#how-does-hissab-ai-work-and-how-does-it-ensure-accurate-results)

> Hissab AI uses a combination of LLMs and hissab engine to provide accurate results. The LLMs are tuned to understand the context of the calculations and extract calculation intent from the prompts which generate hissab expressions. These expressions are parsed by hissab engine which does the computation to provide the final results.

## Account

[Section titled “Account”](#account)

### Do I need to create an account to use Hissab?

[Section titled “Do I need to create an account to use Hissab?”](#do-i-need-to-create-an-account-to-use-hissab)

# Timezone

You can find current time in any timezone.

now in pst

22 Dec 2025, 16:21:01 pst

today in dubai

23 Dec 2025, 4 dubai

You can also convert any time from one timezone to another.

4 pm ist to denver

3:30 am denver

It is recommended to use city names instead of timezone abbreviations as those are not standardized and can refer to multiple different timezones. Hissab will guess and use one of those timezone.

e.g. CST refers to Central Standard time UTC-06, China Standard time UTC+08 and Cuba Standard Time UTC-05.

You can also calculate specific time of one timezone to another timezone.

10:30 pm ireland to beijing

6:30 am beijing

Tip

Quickly find time difference between two timezones by simply subtracting both zones.

sydney - japan

2 hour

mumbai - london

5 hour 30 minute

# Binary Operations

| >>> Bitwise right shift | 0b10101010 >> 30b10101             |
| <<> Bitwise left shift  | 0b10101010 << 30b10101010000       |

Binary operations can be performed not just on binary numbers but with any number system.

# Number Systems

Most calculations are done using decimal (base 10) number systems, but hissab also supports other number systems.

| Number system                                                                                                  | Examples                       |
| -------------------------------------------------------------------------------------------------------------- | ------------------------------ |

| Binary> Base: 2. To input as a binary number use prefix 0b or 0B followed by the binary number                 | 0b010101 + 0B1010100b111111    |
| Octal> Base: 8. To input as a octal number use prefix 0o or 0O followed by the octal number                    | 0O214562 + 0o2635460o500330    |
| Hexadecimal> Base: 16. To input as a hexadecimal number use prefix 0x or 0X followed by the hexadecimal number | 0x1a2f3d2 + 0Xc323ef40xdd532c6 |

Numbers with any number system can be used same way as a decimal number.

Hissab also supports functions which provides quick way to get complex calculations done in simple syntax.

Functions take on a fix or variable number of parameters as input and output the results using those inputs.

Its syntax is:

> function name(input1, input2, input3,…)’.

Each input can be an expression in itself.

# References & Variables

A cool feature of hissab is that it can store results for any expression in a variable of any name, which can be referenced in any other expression.

myvar = 123 + 234

357

myvar - 100

-100

Here ‘myvar’ is a variable name. There are rules around variable names.

* Variable cannot start from a number or special character, except \_ (underscore).
* It must start from a letter.
* It cannot contain any special character except \_.

abcd123 = 1234

1,234

\_ab = 12

12

my\_var = 34

34

\#ab = 12

12

Variables can hold values with units as well as dates and times.

unit1 = 5 miles

5 mile

time\_then = now + 100 days

2 Apr 2026, 0:21:01

Variable names are case-sensitive.

abcd123 = 1234

1,234

abcd123 = 1234

1,234

Variable names cannot be a unit name or hissab keyword like ‘time’.

time = 1234

1,234

meters = 123

123

time123 = 1234

1,234

Variable declaration must be at the beginning of an expression.

9876 + (myvar = 1234)

11,110

myvar - 9876

-9,876

myvar = 1234

1,234

You can directly reference results from any previous lines without storing it in variables as well by using line (or just l) followed by the line number and no space in between.

You cannot only refer to lines above the current line.

123 + 234

357

50 meters to cm

5,000 cm

123

123

line 2 \*2

4

You can refer to the previous line’s result with the ‘prev’ keyword.

123 \* 2

246

‘prev’ keyword also works if there are empty lines in between.

123 \* 2246

276,258

If you want to add results from all above lines, you can use the ‘total’ keyword. This only works if those results are addable.

# Unit Conversion

Hissab supports unit conversions for most popular units, and then some.

To convert from one unit to another, type your expressions in this format:

> {value} {unit} to {destination unit}

The ‘to’ can be replaced with ‘in’ as well.

> {value} {unit} in {destination unit}

50 meters to miles

0.0311 miles

Convert 50 meters to miles

0.0311 miles

You can perform various mathematical operations with values of different units seamlessly. Hissab will choose the first value’s unit as base and convert all other values to that base unit to calculate final result.

50 meters + 15 miles - 10 km

14 kilometer 190 meter 16 centimeter

However, if you want to force final result to use certain unit, simply add ‘to {final unit}’ at the end of the expression.

50 meters + 15 miles - 10 km to yards

15,518.5477 yards

### Breakdown units

[Section titled “Breakdown units”](#breakdown-units)

The results with large value will be broken down into smaller valued units as seen above. You can also explicitly mention what units the value should be broken down.

50 meters + 15 miles - 10 km to miles,yards,feet

8 mile 1,438 yard 1.643 feet

# MCP Server

# MCP Server

[Section titled “MCP Server”](#mcp-server)

Hissab MCP Server allows you to plug the powerful Hissab Math engine with the LLM of your choice to create a custom math assistant that can reliably and deterministically perform calculations with hallucination-free results.

The MCP server is free for personal and non-commercial use.

Note

For commercial use and custom rate limits, please contact us at <hello@hissab.io>

## Server

## Usage

[Section titled “Usage”](#usage)

Hissab MCP can calculate simple to complex mathematical expressions, including unit conversions, date and time calculations, and more. Checkout the [docs guide](https://hissab.io/guide/introduction) to learn about everything it can do. A lot more examples are available in the [Home Page](https://hissab.io).


Ask simple math problems like:

* Apply a 20% discount to 500 dollars

- Calculate the variance of 45, 56, 67, 78, 89.
- A flight from NYC to London is 7 hours. If I leave at 3:45 PM EST, what’s the arrival time in london?
- I was born on 15th June 1995. How old am I today?


Or complex prompts like:

* I earn $4500 per month, spend $1200 on rent, $600 on food, and $200 on utilities. How much do I save per year?
* I have a SaaS where I provide APIs for use to my customers. The product is using external APIs at the cost of 0.10 per 10K requests My product pricing is $50 per year and it allows fixed number of requests per day. Assuming each customer requests uses 5 external requests, how many maximum requests per day can I allow uses to not make a loss ?
* how much should I pay per month if I want my $50K loan at 4% interest to be paid of in 5 years
* how long will my $450K loan over 4% interest last if I pay $2500 per month and get reliable answers.

…etc etc etc…


You can also Attach and reference your own docs to use the data in it in your calculations. Or use web search to fetch realtime data like currency/stock rates which can be referenced in further calculations.

## AI Agent vs MCP Server

[Section titled “AI Agent vs MCP Server”](#ai-agent-vs-mcp-server)

AI Agent uses custom fine tuned LLMs to provide the best performance and accuracy for math operations. While MCP Server plugs as a tool in any LLM you already use.
